*IF* the Higgs Field gives an explanation for why some particles have mass and others don't, and *IF* the Higgs Boson is a part of this field; then the discovery of the Higgs Boson would be a major breakthrough in supporting the Higgs Field, and thus the continued use of "The Standard Model." If it is NOT found, then scientists are almsot back to the drawing board.
Because of these facts, the Higgs Boson is called, completely erroneously, the particle that creates mass or (worse) the "God Particle." Even the person who first used that term to describe the Higgs Boson hates the use of it.
As of this week, scientists at CERN predict that the existence of the Higgs Boson will be known within a year.
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
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 tau neutrino has mass and is denoted with the symbol μ.
The neutron is a subatomic particle that has mass nearly equal to that of a proton but carries no electrical charge.
Matter
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.
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
