Fun Facts About Chemical Elements

How many protons are in an atom of oxygen?

(A) 6

(B) 8

(C) 16

(D) 20

Answer

The correct answer is (B) 8.

Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.

Oxygen has 8 protons in its nucleus, giving it an atomic number of 8. This means that every atom of oxygen contains 8 protons.

So, the correct answer to the question is (B) 8 protons in an atom of oxygen.
