The neutron has a mass very close to the mass of proton (but not identical).
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.
It is probable an error: the electron has a mass equal with 1/1836 from the mass of proton or neutron.
Normal matter: Proton Anti-matter: Positron
The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton.
The term nucleon is applied to any particle that makes up an atomic nucleus. That means it can be applied to either a proton or a neutron (but only when we are talking about them as the components of an atomic nucleus). The nucleon with the positive charge is the proton. You'll recall that the neutron is a neutral particle; it has no charge.
neutron
An "element" is not a subatomic particle. Your question makes no sense and is therefore unanswerable.Another answer:Since an element is not a subatomic particle, the only answer can be a proton.
Proton has a greater mass than the electron.
The neutron is a subatomic particle that has mass nearly equal to that of a proton but carries no electrical charge.
the neutron
The neutron has the biggest mass; but the mass of proton is very close.
Proton or neutron
among these Electron has the least mass....
Both one proton and one neutron each has a relative mass of 1 a.m.u.
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.

The proton is the subatomic particle which carries the positive charge. It has a charge of +1 and a mass of 1,672 621 637(83).10-27 kg.
