These elements have better catalytic, metallurgical, atomic, electrical, and magnetic properties than other metals. And these elements share many similar properties, due to which it is very difficult to separate them from each other or to identify them separately. It's very important in the areas of technological development, space research, etc. today. Nature-friendly means should be searched for the processing of this so that there is minimal damage to nature along with the development works.
