Does nitrogen or antimony have a smaller ionization energy? Support your answer using atomic structure. (ex: energy levels, attraction, nuclear charge).

Antimony, it increases as it goes across a period and decreases as it goes down a group. Does potassium or lithium have the smaller atomic radius? Lithium, because as you move across a period it gets weaker and down a group, it gets stronger.

since electrons are negative the answer is neagtaive
