WebbPhysical Properties of Lanthanides 1. Density: Density being the ratio of the mass of the substance to its volume, density of d-block elements will be more than the s-block elements. Among the inner transition series, the trend in density will be reverse of atomic radii, ie. density increases, with an increasing atomic number along the period. WebbThe oxidation state of an atom is a measure of the degree of oxidation of an atom. It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge. Isotopes
