According to the periodic table, lithium and nitrogen have the same number of
a. protons.
b. electrons.
c. electron energy levels.
d. protons plus neutrons.

The correct answer is option c. electron energy levels.

Explanation:

Hello!

Let's solve this!

Lithium has an atomic number 3, which means it has 3 electrons, two levels where they are distributed.

Nitrogen has an atomic number 7, that is, 7 electrons distributed, also like lithium, in 2 levels.

After the analysis, we conclude that the correct answer is option c. electron energy levels.
