By the end you’ll be able to

describe the properties of Group 1 metals and explain their reactions with water, oxygen and chlorine in terms of electron loss and the formation of $+1$ ions
interpret and predict trends down Group 1 in reactivity, melting point and softness using atomic radius, shielding and attraction between the nucleus and the outer electron
describe the properties of Group 7 halogens and explain their simple molecular nature, diatomic formulae and coloured appearance or states at room temperature

apply the concept of displacement to halogen reactions and write word or symbol equations for a more reactive halogen displacing a less reactive halide from solution

use simple oxidation state ideas and ionic equations to identify oxidation and reduction in halogen and halide reactions
