- Halogens take electrons from other features with an exceptionally solid force, meaning the pressure to oxidize other elements is sort of powerful. The simplest things from which halogens may take electrons are metals belonging to team one, for instance Na and K, which have just one electron within the outer shell. Thus, when halogens encounter these metals, they immediately go ahead and take electrons for making salts for example NaCl and KI. How can halogens seem inside our eyes?
