Oxidizing Power and Ionization Energy

Halogens

Alkali Metals

🔶 Alkali metals have oxidation states of 0 and +1.
🔶The first ionisation energy decreases down the Group because the outermost electron is getting further from the nucleus and so is easier to remove.

🔶 Fluorine in all its compounds has an assigned oxidation number of -1
🔶 The other halogens have a wide range of oxidation states
🔶 The ionization energy decreases down the group
