Hydrogen protons neutrons electrons

Hydrogen has 1 proton, 0 neutrons, and 1 electron.

#1 Hydrogen Protons

  • Protons = atomic number

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

Hydrogen location on periodic table

The atomic number of hydrogen is 1. Hence, hydrogen has a total of 1 proton.

#2 Hydrogen Neutrons

  • Neutrons = atomic mass – atomic number
Hydrogen neutrons

The atomic mass of hydrogen is 1.00784, so we’ll take the roundup value as 1. And the atomic number of hydrogen is also 1.

Subtract the atomic number (1) from the atomic mass (1). Hence, hydrogen has a total of 1 – 1 = 0 neutrons.

#3 Hydrogen Electrons

  • Electrons = atomic number
Hydrogen electrons

The atomic number of hydrogen is 1. Hence, hydrogen has a total of 1 electron.
