What do elements in the same group have in common?

The elements in Group 1 are known as:

One group of similar elements is the alkali metals: lithium, sodium, potassium, rubidium and caesium. They are all highly reactive. For example, if you add them to water they explode.Determine why it helps scientists to group these elements together.A discovery about one element in the group is likely to extend to the othersThe similar properties are likely to have the same theoretical explanationThe elements in the group are made up of identical atomsThe similar properties might lead to similar uses, so if one element is scarce it might be replaced by another in the groupI'm not sure

True or false? Elements within a group show similar chemical properties to each other.
