Helium has 2 protons, 2 neutrons, and 2 electrons.

Helium protons

  • Protons = atomic number

From the periodic table, find the atomic number of helium.

Helium location on periodic table

The atomic number of helium is 2. Hence, helium has a total of 2 protons.

Helium neutrons

  • Neutrons = atomic mass – atomic number
Helium neutrons

The atomic mass of helium is 4.002602, so we’ll take the roundup value as 4. And the atomic number of helium is 2.

Subtract the atomic number (2) from the atomic mass (4). Hence, helium has a total of 4 – 2 = 2 neutrons.

Helium electrons

  • Electrons = atomic number
Helium electrons

The atomic number of helium is 2. Hence, helium has a total of 2 electrons.
