Question

What factor(s) may be responsible for the ionization energy within a period?

Select all that apply.

The valence electrons are further from the nucleus when moving from left to right.

The valence electrons remain at the same distance from the nucleus when moving left to right.

The diameter of the atom decreases somewhat as electrons are added.

The attractive force of the nucleus increases

Answer 1

1.The attractive force of the nucleus increases as we cross the period from left to right, (this is due to the extra protons) This mean the atomic size will decrease from left to right.
