Adam Collinge Core Chemistry GCSE English 5 cards

Cards in this deck (5)

1How do you tell the amount of electrons an element has using the P. table?By which group it is in, e.g group 1 elements have 1 electron on the outer shell but group 0 electrons will have 8 electrons on the outer shell
2When are atoms much 'happier'?When they have a full shell of electrons
3Why do most atoms want to react?Because most atoms don't have an outer shell
4Why is the less reactive group on the periodic table and why?Group 8 because they have a full outer shell of electrons
5Which group on the P. table is the most reactive and why?Group 1 because they have the least amount of electrons on the outer shells
