2.1.2 Atomic Structure

1. Isotopes of carbon

   • Carbon-12
   • Carbon-13
   • Carbon-14

2. Reactions of isotopes

   • Isotopes of elements have the same reactivity as they differ in neutrons which don't affect the reactivity

3. Protons, Neutrons & Electrons

   • PROTON
     • mass: 1 charge: 1+
   • NEUTRON
     • mass: 1 charge: 0
   • ELECTRON
     • mass: 1/2000 charge: 1-

4. Isotopes

   • elements with the same atomic number but different mass numbers

5. Atomic Structure of ions

   • ions have unbalanced number of protons and neutrons so the charges don't balance out
