In the atom the electron is the lightest.
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
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.
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
The tau neutrino has mass and is denoted with the symbol μ.
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
among these Electron has the least mass....
Both one proton and one neutron each has a relative mass of 1 a.m.u.

Yes, a neutron has mass. The mass of a neutron is slightly greater than the mass of a proton, which is another subatomic particle found in the nucleus of an atom. Neutrons and protons are both much more massive than electrons, which are the smallest subatomic particles.
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
The tau neutrino has mass and is denoted with the symbol μ.
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.
The neutron is a subatomic particle that has mass nearly equal to that of a proton but carries no electrical charge.
