Question

By which common name are the elements of Group $1$ and Group $17$ called?

Answer 1

Common name are the elements of Group $1$ and Group $17$

Group $1$ : Alkali metals

• The same group elements are done based on the outermost shell electrons. The bonding is done by this outermost shell electrons.
• Group $1$ is of alkali metals and number of electrons for bonding is $1$.
• The metals in group $1$ are alkali in nature because the valance shell electron make it octet configuration by donating the electron. So they are called as Alkali Metals.

Group $17$ : Halogens

• Group $17$ is of halogens and number of electrons for bonding is $7$.
• Flourine, Chlorine, Bromine and Iodine are the group $17$ elements
• These elements form salts and hence known as Halogens.
