Particles smaller than an atom are known as subatomic particles. The deuteron is a subatomic particle that contains a neutron and a proton. The atom is known as deuterium and its nucleus is known as deuteron. In this session, let us know more about deuteron, its mass, as well as the difference between deuteron and deuterium.

What is Deuteron?
The deuteron is a stable particle composed of neutron and proton. It is denoted by symbol D or 2H or Hydrogen-2. Deuteron mass is expressed using the atomic mass unit (amu) or electron volts(eV). Deuteron has a charge +1e.
Mass of Deuterium
| Mass of Deuteron in amu | mD = 2.013553212745(40) u |
| Deuteron mass in MeV | mD = 1875.612 928(12) MeV |
Difference Between Deuteron and Deuterium
| Deuteron | Deuterium |
| Deuteron is the nucleus of Deuterium | Deuterium is an isotope of hydrogen |
| Deuteron is represented by 2H+ | Deuterium is represented by 2H or D |
Hope you have learnt about Deuteron in atomic theory. Along with, the difference between Deuteron and deuterium, the mass of Deuteron in two units namely- Deuteron mass in amu, Deuteron mass in MeV.
