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 lightest subatomic particle is the electron.
The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
Acceleration = force/mass
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
A particle that has a mass of 1 and a charge of 1 plus is a proton.
The tau neutrino has mass and is denoted with the symbol μ.
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.
The Atomic Mass is the addition of all the protons and neutrons in an atom of an element.
To convert the mass of a single particle to the mass of one mole of particles, you multiply the mass of the individual particle by Avogadro's number, which is approximately (6.022 \times 10^{23}) particles per mole. This calculation provides the total mass of one mole of that specific particle. For example, if a single particle has a mass of (m) grams, the mass of one mole would be (m \times 6.022 \times 10^{23}) grams.
The neutron is the particle of an atom that has zero charge. It is located in the nucleus along with protons and contributes to the overall mass of the atom without affecting its charge.
