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.
