Helium atom has an atomic mass of 4 u and two protons in its nucleus. How many neutrons does it have?

Open in App

Solution

Mass of helium atom= number of proton + number of neutron

Or

Number of neutron = Mass of helium atom - number of proton

Given, the mass number = 4
Therefore,
Number of neutron = 4- 2
Number of neutron = 2
Thus, number of neutron in helium atom = 2
