WebOct 22, 2024 · The halogens are the six nonmetallic, highly reactive elements under Group VIIa (column 17) of the periodic table. They’re very strong oxidising agents, which means they take electrons from other substances. They’re also very reactive and usually form salts with Group 1a, i.e. the alkali metals. The name halogen literally means salt-producing. WebThe halogens all have relatively high ionization energies, but the energy required to remove electrons decreases substantially as we go down the column. Hence the heavier …
