Sub-Atomic Particles

Sub-Atomic Particles

1. Protons

   • Have a positive Charge
   • Have a mass of 1
   • Can be found in the nucleus
   • The atomic number tells you how many are in an arom

2. Neutrons

   • Can be found in the nucleus
   • Neutral
   • The number of neutrons in an atom can be found by taking the atomic number from the mass number
   • Have a mass of 1

3. Electrons

   • Can be found orbiting the nucleus
   • Have a negligable mass
   • Have a negative charge
   • There are the same number of electrons as protons in an atom
