Chemistry

1. Atoms, Elements and the periodic table

   • Alkaline Metals (Group 1)
     • Lithium, Sodium, potassium, rubidium, caecsium and francium
   • Halegeons (group 7)
     • Fluorine, chlorine, bromine, iodine, astatine
   • Earth Metals (Group 2)
     • Beryllium, magnesium, calcium, strontium, barium, radium
   • Transition metals (middle block)
     • All the rest from Scandium - polonium

2. Particles

   • Solid
     • has a distinct shape, can be contorted
   • Liquid
     • Takes the shape of the container
   • Gas
     • No distinct shape
   • Heating curve
     • Cooling curve

3. Chemical Changes

   • Adding an acid to an alkali
   • Burning a wooden splint
   • A chemical change is when the changed object cannot be brought back to its original form

4. Physical Changes

   • Melting Ice Cream
   • Melting ice
   • A physical change is when the changed object can be recovered to its original form
