When two atoms are bonded and have a large difference in electronegativity:
HELP PLEASEEE

Answers

Answer:

Second option - The bond is very polar

Explanation:

Electronegativity of an basically refers to the degree at which an electron is able to attract electrons to itself.

There are different types of bonds between atoms, depending on the electronegativity of the atoms.

When there is a large difference in electronegativity, it pretty much means that one atom would draw electrons more than the other. When this happens, the bond is said to be polar because there is uneven distribution of the charges.

The second option is the correct answer in thus question.

As you move down a group of the periodic table how does the atomic radius of the atoms change

Answers

Answer:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements. In general, the size of an atom will decrease as you move from left to the right of a certain period.

Mariah has the formula reversed; it should be the total number of sections over the numbers greater than 7.Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.Mariah should multiply by the number of sections in the spinner rather than the total number of spins.Mariah calculated the prediction correctly and did not make any mistakes.
