The first member of the lanthanide series is lanthanum . True / False

The first member of lanthanide series is not Lanthanum but Cerium. Hence the statement that 'The first member of the lanthanide series is lanthanum' is a false statement. Lanthanum is only included in the study of lanthanoids as its properties closely resemble the properties of the inner transition elements. Moreover, the inner transition elements involve the filling of 'f' orbitals and in lanthanum, the valence electron is present in d orbital and not f.
