periodic group properties
group 0- noble gases
mpt&bpt goes up as you move down
low density used in air ships, light bulbs an advertising signs
unreactive
group 1- alkaline metals
mpt&bpt goes down as you move down
low density, float on water
more reactive as you move down
forms +1 ions
form compounds of whte solids and dissolve in water
forms hydroxides and hydrogen gas
group 7- halogens
non metals, diatomic
react with metals and form ionic compunds
mpt and bpt goes up as you move down
less reactive as you go down
react with non metals and form covalent compounds
form haildes that makes water acidic when dissolved
group 4- transition metals
dense
ions with different charges
high melting point
less reactive with water and air
form coloured compounds
