Well Actinide Metals are radioactive.They have A LOT of elements. There is also is a series through 15 chemical elements.Some Actinide Metals are thorium,uranium,neptunium,plutonium and a lot more.
Lanthanide Metals are one of the largest non-reactive metals.They are also so soft you could even cut it with a knife.Some Lanthanide metals are cerium,lutetium,and thorium.
A special element in Alkali Metal is Hydrongen.They are really reactive,how they are reactive is because they have one electron in there outer shell.
The elements are metallic.They are also reactive.Since they are reactive they are not found in nature.They also use oxidation numbers of +2 to make them very reactive.Some Alkaline-Earth Metals are beryllium,magnesium,calcium and more.
They are in a lot of electronic technologies.Such as T.Vs,fluorescent light bulbs,cell phones,and computers.Some of there metals are europium,erbium,lutetium,thulium,and a whole lot more.
