Lastly radium, which is a very dangerous radioactive source. Radium is very rare and its 0.0000001 parts per million abundance of this element is mainly found ins pitchblende uranium extracts. Used to make self-luminous paints but had to be replaced due to its dangerous radioactive source.

Group 2 alkaline earth metals, with the exception of radium, are essential and vital to the eco-diversity and commercial products of today’s world. Have been used for a variety of situations for humans and have been huge resources for the evolution for humans.
