The subatomic particle that has a negative charge is the electron. Out of the three subatomic particles that compose an atom, the electron has the smallest mass.

Particle physics describes the universe at the smallest scale. This includes subatomic particles, like protons and neutrons, as well as elementary particles, like quarks and electrons, which make ...

This is despite the fact that subatomic charm quarks are about 1.5 times more massive than the proton, itself. When charm quarks are present, they carry about half of the proton’s mass.

The Standard Model organizes the subatomic world into two broad categories of particles, known as fermions and bosons, according to the University of Tennessee, Knoxville.

Scientists can determine the mass of subatomic particles that are built from quarks by looking at the particles' energy and momentum in four-dimensional spacetime. One of the quantities that ...

Neutrinos are a type of subatomic particle. They don’t have an electric charge, have a small mass, and are left-handed (a physics term meaning the direction of its spin is opposite to the ...

Protons: Protons are positively charged particles found in the nucleus (central core) of an atom. They have a relative mass of 1 and a positive charge of +1.

It consists of atomic nuclei with a charge of 10 18 to 10 20 electron volts, making them the most energetic particles found in nature.

CERN physicists observed matter-antimatter imbalance in a baryon. Antiparticles possess the same mass as matter but opposite charge. The Big Bang should have created equal matter and antimatter.

Since the start of the 20th century, physicists have discovered a veritable zoo of subatomic particles. Matter can be both wave and particle.
