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.

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).

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.

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

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 neutron is one of the three subatomic particles that make up an atom. It exists in the nucleus of the atom alongside protons and makes up an atom's atomic mass with protons.

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.

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.

Subatomic Particles: Science has only known about subatomic particles for a little over a century. It was once believed the atom was the smallest, indivisible unit of matter. However, the …
