Q:

What subatomic particle has the least mass?

A:

Quick Answer

An electron has the least mass of any subatomic particle, with a mass of 9.1 x 10^-31 kilograms per electron. Electrons are found in the electron cloud, an area that surrounds the nucleus of an atom.

Full Answer

Electrons hold a negative charge equal to the positive charge found in protons of the nucleus. They generate an electric field, exerting an attraction towards particles with positive charge such as protons or a repulsion against particles with negative charge. When electrons are in motion, they generate a magnetic field. Sir John Joseph Thompson discovered the existence of electrons in 1896 through experiments involving cathode rays.

  • Q:

    Which atomic particle has the least mass?

    A:

    Hydrogen is the atomic particle that has the least mass. An atom is made of a combination of subatomic particles known as protons, neutrons and electrons. The combined mass of these particles determines the mass of the atom. Hydrogen has the least number of subatomic particles, thus the least mass.
