2018/4/6· 2 Ca + O 2 → 2 CaO (calcium oxide) 4 Al + 3 O 2 → 2 Al 2 O 3 (aluminium oxide). The transition metals (such as iron, copper, zinc, and nickel) are slower to oxidize because they form a passive layer of oxide that protects the interior. Others, like palladium, platinum and gold do not react with the atmosphere at all.

What Is the Most Reactive Metal on the Periodic Table?

2019/10/8· Updated October 08, 2019. The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium. Cesium reacts explosively with water, though it is predicted francium would react even more vigorously.
