The successive elements belonging to the 3d-series have the same number of electrons in the d-sub-shell. The elements are

The number of orbitals in d sub-shell is

Atom of seven elements A,B ,C, D, E,F and G have a different number of electronic shells but have the same number of electrons in their outermost shells. The element A and C combine with chlorine to form an acid and common salt respectively. The oxide of element A is liquid at room temperature and is a neutral substance while the oxides of the remaining six elements are basic in nature . Based on the above information, anwer the following question given ahead : Will element A to G belong to the same period or same group of the periodic table ?
