Question

2. What are the similarities in properties of elements in Halogen family?
Why does Inert gases placed in Zero group?​

Answer 1

Answer:-

Halogens share many similar properties including:

•They all form acids when combined with hydrogen.

•They are all fairly toxic.

•They readily combine with metals to form salts.

•They have seven valence electrons in their outer shell.

•They are highly reactive and electronegative.

and-

Inert gases have their completely filled valence shell with octet of electrons. So they have 0 valency and thus non reactive in nature thus placed in Zero Group.
