Which property has a trend similar to that of electronegativity?
A. First ionization energy
B. Atomic radius
C. Ionic radius
D. Atomic mass
Answer:
a
Explanation:
There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Therefore, the correct option is option A.
What is periodic table?Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.
Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can discover the new elements that are not being discovered yet.
Along period, electronegativity increases. along group electronegativity decreases. The same trend is followed by first ionization energy in periodic table.
Therefore, the correct option is option A.

The density of butter is 0.86 g/cm3. what is the mass of 240 cm3 of butter?
Answer:
mass= 206.4 g
Explanation:
Density= mass/volume
0.86=x/240
x=240×0.86
=206.4g
The density of butter is 0.86 g/cm³. 206.4g is the mass of 240 cm³ of butter. The phrase "specific volume" is occasionally used in thermodynamics to refer to a substance's reciprocal of its density.
Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units). For example, the density of air is 1.2 kilograms per cubic metre.
Density= mass/volume
0.86=x/240
x=240×0.86

. A car accelerates at a constant rate in a straight line.
The velocity of the car increases from 4.9 m/s to 6.4 m/s in 3.00 minutes.
Calculate the acceleration of the car.
Give your answer to 3 significant figures.
Answer:
The acceleration of the car is 0.0273.
Explanation:
We can find this by using the acceleration formula which is:
a = ( vf - vi ) / Δt
a is acceleration.
vi is the initial velocity.
vf is the final velocity.
When we substitute into the equation we get. . .
a = ( 6.4 - 4.9 ) / 3
and when we solve this equation we get 0.02734

Mercury, which has 1/3 the gravity of
Earth?
A. more than on the Earth
B. less than on the Earth
C. the same as on earth
Answer:
The same as on earth
Explanation:
mass is the amount of matter in an object and the mass of an object is always the same at any point in time
gravity will only have effect on the weight and not the mass.
so assuming the question was talking about the weight, then we can say the weight will be lesser on Mercury

Based on their definitions, electron affinity could be considered the opposite of
Based on their definitions, electron affinity could be considered the opposite of electron affinity. This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons.
What is meant by electron?The electron is a subatomic particle with a negative one elementary charge electric charge. Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically regarded to be elementary particles.
An electron is a negatively charged subatomic particle that can exist either free or bound to an atom (not bound). Along with protons and neutrons, electrons are one of the three primary types of particles that make up an atom. Together, protons, neutrons, and electrons make up the atom's nucleus.
This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons. Conceptually, this is the polar opposite of electron affinity.

A Rectangular Prism has a height of 4cm, a width of 5cm, a length of 1.2 cm, and a mass of 85,000 g. What is it's density?
A. .00000035416 g/cm3
B. 00035416 g/cm^3
C. 354.16 g/cm^3
D. 3541.6 g/cm
Answer:
The answer is D.
Explanation:
Volume (V) = l x w x h
V = 4 x 5 x 1.2
V = 20 x 1.2
V = 24
Density = Mass/Volume or D = M/V
D = 85,000/24

2. What is the difference between a Chemical Process and a Physical Process?
3. How many electrons fit in each shell around an atom?
Answer:
a) Diamond can indeed be set on fire since it is made of carbon. ... Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right.
b) In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
c) Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
