If you mean the omega baryon, it's a baryon, which means it has mass by definition ("barytes" is Greek for "heavy").
Otherwise ... I've never heard of an "ohm particle" and frankly it sounds like the sort of thing that would feature in a particularly crackpotty reimagination of physics, along the lines of magnetic immortality bracelets and the "plutonium atom totality" nonsense.
A particle without mass is called a massless particle. Massless particles travel at the speed of light and do not experience gravitational forces. They have energy and momentum, but no rest mass. Examples of massless particles include photons (particles of light) and gluons (particles that mediate the strong nuclear force).
The photon is a particle with almost no mass. It is the carrier particle of the electromagnetic force and travels at the speed of light.
The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
Acceleration = force/mass
An alpha particle is larger and has more mass than a beta particle. An alpha particle is made up of two protons and two neutrons, giving it a mass of 4 atomic mass units, whereas a beta particle is much lighter and has a mass close to that of an electron. Size-wise, an alpha particle is larger in diameter compared to a beta particle.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
The tau neutrino has mass and is denoted with the symbol μ.
A proton is a particle that has a mass of 1 and a charge of 1 plus.
you can't get mass you can acquire it mass is govern by a particle known as the Bassa Nova Higgs the smallest particle in the mutiverse or universe.
This particle is the neutron.
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
