As you go down the alkali metals group, the elements become m â¦ ore reactive. So Francium is the most reactive alkali metal. Also, Halogens, because they already have 7 electrons and only need to gain one in order to have a stable valence level of 8. As you go up the halogens group, the elements become more reactive.
Silver (Ag) and copper (Cu) are some of the most efficient metals and are often used in electronics. 2. Reactivity: Metals are very reactive, some more than others, but most form compounds with other elements quite easily. Sodium (Na) and potassium (K) are some of the most reactive metals. A metal like iron (Fe) forms iron oxide (Fe2O3), which you know as rust. 3. Chemical: It gets a little complex here.
