Question

Explain the change in ionization energy across a period.
Please provide a valid reason, and don't answer if you don't know... (16 points) also, I can't find the "mark as the branliest" button on my screen (so im soz if I cant mark you as one because of this glitch in my page.) but i would really be thankful for your help!!

Answer 1

Answer:

As you move across a period, first ionization energy increases. WHY? - As you move across a period, the atomic radius decreases, that is, the atom is smaller. The outer electrons are closer to the nucleus and more strongly attracted to the center.
