7. Think and discuss: As you move down a group, you will recall that the radius increases.

Why do you think an increase in atomic radius would result in a lower

ionization energy?

8. Think and discuss: As you move across a period, you will recall that the radius decreases.

Why do you think a decrease in atomic radius would result in a greater ionization energy?

9. Predict: Electron affinity (EA) refers to the energy released when an electron is added to

an atom. This release of energy is always expressed as a negative value. The greater the

magnitude of the negative value, the greater the attraction for electrons. (An EA of -100

kJ/mol would indicate a stronger attraction for electrons than an EA of -50 kJ/mol.)

How do you think the size of an atom will affect its ability to attract additional electrons?

Answers

Answer:

See explanation

Explanation:

7. As we move down the group more shells are added. The addition of more shells means that the atom becomes larger and the outermost electron is now at greater distance from the nucleus and screening effect becomes very important. This greater screening effect of the inner electron reduces the magnitude of effective nuclear charge on the outermost electron thereby lowering the ionization energy.

8. As we move across the period, the effective nuclear charge increases without a corresponding increase in the number of shells. As a result of this, the outermost electron becomes more tightly bound to the nucleus as the atom becomes smaller and atomic radius decreases causing a rise in the ionization energy from left to right across a period.

9. Actually, the smaller an atom is the greater its electron affinity. The smaller the atom is, the more the outermost shell is drawn closer to the nucleus and this means that the atom is better able to attract electrons to itself.

It is due to the size of atom which varies its force of attraction.

As you move down a group, the atomic radius increases due to addition of more number of shells in an atom.  This increase in atomic radius would result in a lower  ionization energy because the valance electron is farther from the nucleus and held with weak attractive force so less energy is required to remove it.

While on the other hand, as we move from left to right in a periodic table the atomic radius decreases due to addition of more electrons which shrinks the atom and brought the valance shell closer to the nucleus so it becomes harder to remove an electron because the nucleus held these electrons very tightly.

The size of an atom will affect its ability to attract additional electrons because of its force of attraction. Atoms with small radius has more ability to attract electrons due to higher force of attraction as compared to higher atomic radius atoms.

Crust-In geology, the crust is the outermost solid shell of a rocky planet.

Mantle-A mantle is a layer inside a planetary body bounded below by a core and above by a crust.

Core-is the innermost part of the earth, comprised of the inner core, at the center of the earth, made of iron; and b) the outer core, which surrounds the inner core, made of iron and magma.

Lithosphere-rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle.

Athenosphere-the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.

Mesosphere-the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.

Sea floor spreading-the formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side.

Plate Tectonics- a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.

Tectonic plates- A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. ... By contrast, oceanic crust is composed of basaltic rocks, which are much denser and heavier.

Convergent boundary- A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction.

Divergent boundary- In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other.

Transform boundary- A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal.

Radioactive decay- a radioactive process in which a nucleus undergoes spontaneous transformation into one or more different nuclei and simultaneously emits radiation, loses electrons, or undergoes fission.

Subduction zone- Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle.

Continental drift- Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.

Deformation- the action or process of changing in shape or distorting, especially through the application of pressure.

Folding- A fold is a bend in the rock strata. Folding: Is a type of earth movement resulting from the horizontal compression of rock layers by internal forces of the earth along plate boundaries.

Fault- A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. ... Earth scientists use the angle of the fault with respect to the surface (known as the dip) and the direction of slip along the fault to classify faults.

Shear stress- Shear stress is the stress component parallel to a given surface, such as a fault plane, that results from forces applied parallel to the surface or from remote forces transmitted through the surrounding rock.

Tension- in physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar one-dimensional continuous object, or by each end of a rod, truss member

Compression- Compression, decrease in volume of any object or substance resulting from applied stress. Compression may be undergone by solids, liquids, and gases and by living systems.

Syncline- a trough or fold of stratified rock in which the strata slope upward from the axis.

Anticlines- an arch of stratified rock in which the layers bend downward in opposite directions from the crest.

Law of Universal Gravitation- Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Law of superposition- Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.

law of conservation of mass- The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Answers

Answer:

4.99 x 10⁻⁷ meters or 499 nanometers

Explanation:

Use the formula:

λ = c/ν, where λ = wavelength, c = the speed of light (it's constant, 2.998 x 10⁸ m/s), and ν = frequency

λ = (2.998 x 10⁸ m/s)/(6.01 x 10¹⁴ 1/s)

λ = 4.98835 x 10⁻⁷

Round to nearest hundreth and you get 4.99 x 10⁻⁷ meters, or 499 nanometers.

Which statement best describes John Dalton's use of creativity in his work? He reinterpreted and retested Joseph Proust's results. He used a philosophy to conduct his experiment. He recorded his results as four parts of the atomic theory. He rejected Democritus's idea that matter was composed of atoms.

Answers

Answer: The correct statement is that,

'He reinterpreted and retested Joseph Proust's results'

Explanation:

John Dalton was an English chemist who contributed greatly to the field of Chemistry. He published his theory about atom in 1808.

Dalton was the first person to recognize a workable distinction between the fundamental particle of an element (atom) and that of a compound (molecule). The atomic theory generally summaries the laws of chemical composition which includes:

--> law of constant composition and

---> law of multiple proportions.

John Dalton was being creative in his work by reinterpretation and retesting of Joseph Proust's results. Joseph Proust was a French chemist that first discovered the law of constant composition in 1794. This means that many has started working on the atoms before John Dalton discovery.

From the previous works of Proust, he had studied tin oxides and found that their masses were either 88.1% tin and 11.9% oxygen or 78.7% tin and 21.3% oxygen (these were tin(II) oxide and tin dioxide respectively). Dalton retested and noted from these percentages that 100g of tin will combine either with 13.5g or 27g of oxygen; 13.5 and 27 form a ratio of

Dalton reinterpreted it by finding an atomic theory of matter that could elegantly explain this common pattern in chemistry – in the case of Proust’s tin oxides, one tin atom will combine with either one or two oxygen atoms. I hope this helps, thanks.
