Properties and Characteristics of Subatomic Particles Each subatomic particle has its own unique properties and characteristics. These properties include their charge, mass, and spin.

What are the fundamental particles of an atom? Learn about the fundamental particles, also known as elementary particles, and the types of particles.

J.J. Thomson's cathode ray tube experiment discovered the subatomic particle the electron. Prior to the experiment, it was not known that atoms were composed of further particles.

James Chadwick's contribution to the atomic model was his discovery of the neutron. The neutron is a neutrally charged subatomic particle that is about the same mass as the proton. Both …

The nucleus contains two subatomic particles: the protons and the neutrons. Protons are positively charged particles with a mass of approximately 1 amu (atomic mass unit).

He developed the Heisenberg uncertainty principle, which states that it is not possible to precisely and simultaneously measure both the velocity and position of a subatomic particle like an …

The subatomic particle involved in chemical bonding is the electron. Electrons are the smallest of all subatomic particles and orbit the nucleus in... See full answer below.

Explore the properties of subatomic particles in this informative video lesson. Discover the unique characteristics of each type, then take a quiz for practice.

The subatomic particle with almost no mass is the electron. The approximate mass of the electron is 1/1840th of an atomic mass unit. This is...

Lepton History The first lepton, and the first subatomic particle, to be discovered was the electron. The electron was discovered by J.J. Thomson in 1897 while he experimented with cathode rays.
