- Halogens acquire electrons from other elements with an exceedingly robust power, meaning the drive to oxidize other features is sort of solid. The easiest aspects from which halogens may take electrons are metals belonging to group one, which include Na and K, that have only one electron in the outer shell. As a result, when halogens experience these metals, they straight away go ahead and take electrons to produce salts including NaCl and KI. How do halogens appear inside our eyes?
