Question

What is formed when halogens combine with each other?

Answer 1

Halogen family:

• The elements present in halogen family belongs to group $17$ in the periodic table.
• Example: Fluorine $\left(\mathrm{F}\right)$, Chlorine $\left(\mathrm{Cl}\right)$, Bromine $\left(\mathrm{Br}\right)$ and Iodine $\left(\mathrm{I}\right)$.

Interhalogen compounds:

• When halogens combine with each other, then they form interhalogen compounds.
• For example: Chlorine monofluoride $\left(\mathrm{ClF}\right)$, Bromine trifluoride $\left({\mathrm{BrF}}_3\right)$, Iodine pentafluoride $\left({\mathrm{IF}}_5\right)$, Iodine heptafluoride $\left({\mathrm{IF}}_7\right)$.

Therefore, interhalogen compound is formed when halogens combine with each other.
