Answer

Explanation:

Step1: Count the electrons

The first shell can hold 2 electrons, the second and third shells can hold 8 electrons each. Counting the dots (electrons) in the structure, we have 2 + 8+ 8 = 18 electrons.

Step2: Match with element

The number of electrons in a neutral atom is equal to its atomic number. Argon (Ar) has an atomic number of 18.

Answer:

argon (Ar)
