Why does the ionization energy decrease as you move down a group on the periodic table? More neutrons in the nucleus

More electrons in the outer energy level

The size of the atom increases

1) As you move down a group, first ionization energy decreases. WHY? Electrons are further from the nucleus and thus easier to remove the outermost one. 2) As you move across a period, first ionization energy increases.

so i think it is b

Explanation:

i think its 5049.

i hope this !

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
