Question

7 fill in the blank 1 point elements in the same choose your answer... have the same highest occupied energy level. thus, their valence electrons are about the same distance from the nucleus. the nucleus with the greatest number of choose your answer... will have the choose your answer... attraction on the valence electrons.

Explanation:

Elements in the same period have the same highest - occupied energy level. The number of protons in the nucleus determines the nuclear charge, and a greater number of protons results in a greater attraction for valence electrons.

Answer:

1. period
2. protons
3. greatest
