Atomic Structure

• Atoms contain three smaller particles
• These particles are called Protons,Neutrons and Electrons
• Each particle has a different charge.
• Protons
• Protons have a Relative Charge of +1
• The Mass Number of protons is 1
• Neutrons
• Neutrons have a Relative Charge of 0
• The Mass Number of neutrons is 1
• Electrons
• Electrons have a Relative Charge of -1
• The Mass Number of electrons is very small/-1
