Deuterium or hydrogen-2, symbol D, is also known as heavy hydrogen. There are two stable isotopes of hydrogen; one is protium or hydrogen-1 and the other is deuterium or hydrogen-2. The nucleus of deuterium is called a deuteron which contains a proton and a neutron, whereas the protium doesn't contain any neutron in its nucleus. Deuterium is abundantly available in the oceans, one deuterium atom is found per 6420 atoms of hydrogen.
Deuterium is a stable atomic particle containing a proton and neutron. It is denoted by D or 2H and is called Hydrogen-2. Mass of deuteron is expressed in terms of an atomic mass unit (amu) or electron volts (eV). The Charge of deuteron is +1e. This is due to the presence of protons.
The atomic mass unit (amu) is defined as the 1/12 mass of a carbon-12 atom. The carbon-12 or C-12 atom consists of 6 neutrons and 6 protons in its nucleus. Precisely, one amu is the average mass proton and neutron at rest.
If we want to convert the binding energy in terms of MeV (mega electron volt) per nucleon, will have to apply the conversion factor which is given by
1 MeV = 1.602 x 10-13 J
One amu is equivalent to energy of 931.5 MeV.
One AMU is the average of the rest mass of a neutron and the rest mass of a proton. This mass is approximately equal to 1.67377 x 10-27 kilogram (kg), or 1.67377 x 10-24 gram (g). The mass of an atomic particle in terms of amu is approximately equal to the number of protons and neutrons in its nucleus.
Million Electron Volts
MeV is the abbreviation for mega-electron volt, and mev is the abbreviation for million electron volts.
A MeV or Mega electron-volt is 1 million times of an eV. One eV (electron-volt) is defined as the energy gained by an electron (or any other charged particle having a charge equal to that of an electron) when it passes through a potential difference of 1 volt. In SI unit 1eV is equal to 1.6*10-19 Joules.
1. What is the Difference Between Deuterium and a Deuteron?
Ans- Deuterium is an atom; it is an isotope of hydrogen, while deuteron is the nucleus of deuterium.

This nucleus contains a neutron and an electron. The deuterium isotope is represented by 2H or D, whereas the deuteron is represented by 2H+ which is similar to the representation of a proton (H+).
Since deuterium is an isotope of hydrogen, one of its compounds, the deuterium oxide or H2O2 is cheaply available and is heavily used by chemists as an organic anion.
2. Whose Mass is Greater, Proton or Deuteron.
Ans- The mass of a deuterium atom is greater than that of a proton; this is because of the presence of a neutron in the deuterium. Also, the mass of a neutron is a little bit more to that of a proton. This is why the mass of deuterium is almost twice of size to that of a proton.

3. Is it Possible to Separate a Charge From a Mass?
Ans- Electric Charge is one of the intrinsic properties of matter. It is one of the fundamental quantities which come into existence due to the presence of an excess number of electrons or deficiency of electrons, or that of protons. A charge is a property of matter, but is not a physical entity. The electric charge originates due to the presence of some mass, and without any mass charge cannot exist as there will be no source to produce it.
Electric charge is an intrinsic characteristic of the fundamental particles like protons and electrons which makes up the basis of matter, and hence the charge will automatically come out from this particle wherever they exist. So it is not practically possible to separate electric charge from mass as they are coexisting in nature.
Till date, there hasn't been any experimental attempt to separate a charge from a mass. This may be because the equipment being developed these days are not able to measure or distinguish between such properties.
