The atom is the smallest unit on Earth. It is the basic component of any type of matter. It cannot be broken down or sectioned. Protons, neutrons and electrons make up the subatomic particles of an atom. The three subatomic particles determine the overall charge of an atom, the chemical ...
of its protons and neutrons. These are the two largest of the three subatomic particles in an atom and both are found in the nucleus. The smallest subatomic particles, the electrons, orbit the nucleus but have so little mass that they do not really contribute to the mass of the atom. ...
Atom themselves are composed of three elementary particles. Since these particles reside inside an atom, they are also called subatomic particles.Answer and Explanation: The three primary subatomic particles are electrons, protons, and neutrons. The charge ...
1.One of the three basic particles in an atoms. It is found in the nucleus and has zero charge. 2.A subatomic particle with roughly the mass of a proton and no electric charge. Dictionary of Unfamiliar Words by Diagram Group Copyright © 2008 by Diagram Visual Information Limited ...
4.2 The Structure of an Atom Atom is the smallest particle of an element. Atoms cannot be divided into anything smaller. What is an atom made of? Three subatomic particles: – Proton – Neutron – electron + PROTONS + Positively charged subatomic particle Found in the nucleus of an atom –...
An atom can be an ion, but not all ions are atoms. These are the important differences between an atom and an ion.

indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. We now know that atoms are made up of three particles known as subatomic particles: protons, neutrons and electrons — which are composed of even smaller particles, such as...
