  • vertical columns - groups
  • Horizontal rows-periods
  • Alkali metals - group 1/one electron in the outer shell
  • reactions- alkali metals
  • The alkaline metals -group two- 2 electrons in the outer shell/nit as reactive as group 1
  • Halogens - group 7- one electron short to be stable, they are very reactive
  • Group 8 - noble gases - full outer shells of electrons - o electrons in the outer shell - not reactive
  • When atoms lose or gain electrons they become charged particles and are called ions.
