Back

It increases.

Front

What is the trend of ionization energy as you move down a group in the periodic table?

Back

It decreases.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy decreases.

Front

What is the general trend of metallic character in the periodic table?

Back

It increases from top to bottom and decreases from left to right.

Front

What is the significance of the octet rule in relation to electronegativity?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
