Atomic Structure

Do you know the charge, location and mass of each subatomic particle?

Protons Positive subatomic particle found in the nucleus
Electrons Negative subatomic particles found in the electron cloud
Neutrons Neutral subatomic particles found in the nucleus
Element's Identity Number of protons (or Atomic Number)
Mass Number = Protons + Neutrons
Number of Neutrons = Mass Number - Protons
Electron Cloud The negatively charged area surrounding the nucleus
Nucleus The positively charged dense center of an atom that contains protons and neutrons
Valence Electrons Electrons located on the outermost energy level; Determine reactivity
Negative The overall charge of the electron cloud
Neutral Means no charge
Positive The overall charge of the nucleus
Subatomic Partilces Protons, Neutrons and Electrons
Atom The smallest unit of matter
