Atomic Structure

Atomic Structure

1. experiment

   • Flame test
   • precipitation test

2. definition

   • the basic parts
     • Electrons
     • Neutrons
     • Protons
     • Isotopes
       • radioactive decay
         • gamma rays
         • alpha particles
         • beta particles
       • Isotopes: Atoms with the same number of protons but different number of neutrons are called isotopes.
         • Radio-isotopes are atoms with a large number of neutrons
         • uses of isotopes:
   • Mass number: number of protons + number of neutrons
   • Number of neutrons: mass number - number of protons

3. problem solving calculations

4. diagrams

   • oxygen
   • potassium
