Question

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.

Answer 1

Lithium and nitrogen have the same electron energy levels, actually 2 levels.

Answer 2

The correct answer is option c. electron energy levels.

Step-by-step 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.
