A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
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 tau neutrino has mass and is denoted with the symbol μ.

The subatomic particle that has a mass slightly less than that of a neutron is the proton. While both protons and neutrons are nucleons found in atomic nuclei, the neutron has a slightly greater mass, making the proton's mass approximately 0.938 GeV/c² compared to the neutron's mass of about 0.939 GeV/c². This slight difference in mass plays a crucial role in nuclear interactions and stability.

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.

Protons and neutrons have the mass of 1 amu.
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
Both one proton and one neutron each has a relative mass of 1 a.m.u.
