Elements in the same group of the Periodic Table have the same number of valence electrons, or electrons in the outer shell. Therefore, they have very similar chemical properties.

For example, Group 1 metals are called alkali metals. They all react with water to form hydrogen and their respective alkalis. Group 7 elements are called halogens, and group 0 is called noble gases.

The question is a bit ambiguous, but I will take it to mean 'what do the elements of a particular group have in common?' The answer is valence, or, in other words, the number of electrons in the outer shell.
