Question

define charge density of a inner transition metal ion

Answer 1

The inner transition elements are two series of elements known as the lanthanoids (previously called lanthanides) and actinoids (previously called actinides). They are usually shown below all the other elements in the standard view of the periodic table, but they really belong to periods 6 and 7. The lanthanoid series consists of the 14 elements cerium through lutetium (atomic numbers 58–71), which immediately follow lanthanum
