The elements of group 1
WebGroup 3 elements have a higher density than Group 1 or 2 elements. In the outer shell, there are 1-2 electrons. Actinides and Lanthanides. Lanthanides, also known as rare earth elements, have periods 6-7 and are soft and malleable with high conductivity; the only actinides found in significant quantities on Earth are thorium and uranium. ...
