Question

what are the similarities in the properties of element in Halogen family? ​

Answer 1

The halogens all have the property that they have 7 electrons in their outer shell. For quantum mechanical reasons, there is 'room' for 8 electrons in the outer shell. So the halogens will react rather strongly with elements that have one or two electrons in their outer shell.
