Oxygen atom has 8 electrons, 8 protons and 8 neutrons. Find out the mass number of oxygen atom.

Open in App

Solution

The mass number of an atom = no of protons + no of neutrons
Atomic number of Oxygen = 8
Number of protons = 8
Number of neutrons = 8
Hence, the mass number of an oxygen atom = 8 + 8 = 16
