Question

As the number of electrons added to the same principal energy level increases, atomic size generally

A. increases.

B. decreases.

C. remains the same.

D. varies randomly.

Answer 1

increases electrons form a shell around the nucleaus making it larger

Answer 2

As the number of electrons added to the same principal energy level increases, atomic size generally A. increases.

Because as you add energy levels, the electrons are drawn to the nucleus of the atoms giving them a lesser charge. Thus its atomic size also increases.
