Q. Which accounts for the majority of the mass of an atom?
The nucleus contains the majority of an atom’s mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom’s volume.
Q. What part of an atom has the least mass?
Electrons

Q. Who found the structure of an atom?
Ernest Rutherford
Q. Does a neutron have the least mass?
Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams. Therefore, the number of neutrons in an atom contributes significantly to its mass, but not to its charge. Electrons are much smaller in mass than protons, weighing only 9.11 × 10−28 grams, or about 1/1800 of an atomic mass unit.
Q. What is the mass of a deuteron?
| deuteron mass | |
|---|---|
| Numerical value | 3.343 583 7724 x 10-27 kg |
| Standard uncertainty | 0.000 000 0010 x 10-27 kg |
| Relative standard uncertainty | 3.0 x 10-10 |
| Concise form | 3.343 583 7724(10) x 10-27 kg |
Q. Is mass of proton and deuteron same?
First, the mass of the deuteron is twice that of the proton. Second, the spin of the deuteron, made of two particles, a neutron and a proton that have each a spin ½, has a spin 1 different from the spin ½ of a proton. The electric charge of a deuteron is conversely identical to that of the proton.
Q. What is Deutrons?
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.
Q. Is a deuteron?
Deuteron, nucleus of deuterium (heavy hydrogen) that consists of one proton and one neutron. Deuterons are formed chiefly by ionizing deuterium (stripping the single electron away from the atom) and are used as projectiles to produce nuclear reactions after accumulating high energies in particle accelerators.
