Periodic table groups
Group 2
Alkaline earth metals
not as reactive as group 1 (two outer electrons)
Group 7
Halogens
second most stable
Group 1
Alkaline metals
Reactive (one outer electron)
Group 8
Nobel gases
Stable (full shells)
Transition metals
most of the middle of the table
structure of an atom
netrons
no charge, is there to fill space
Electrons in shell
negative charge
Protrons
positive charge
Dark matter
The fancy way of saying that no one knows what else there is
Three Laws
Laws One: Metal + Acid = Salt + Hydrogen
Pop Test
Law Two: Metal + Carbonate = Water + Carbon Dioxide + salt
Carbonates
Law Three: Acid + Base = Salt + water
Neutralisation
Displacement (The Cheater)
A + BC = AB + C (one moves to someone else, The Swap, which is a very weird form of cheating)
AB + CD = AC + BD
