How does the oxidising power of the group 1 metals vary?
The group one metals all have one electron in their outer shell, so are "electron donors". The further down the group one goes, the higher the electron shell containing the lone electron. The result of this is that this electron is held on to less tightly by the nucleus, and therefore the metals at the bottom of the group are more reactive than those at the top of the group.
