False statement for periodic classification of elements is
(1) The properties of the elements are periodic function of their atomic numbers.
P
(2) No. of non-metallic elements is less than the no. of metallic elements.
W
(3) First ionization energy of elements does not increase regularly with the increase in atomic number in a period.
(4) d-subshell is filled by last electron with increasing atomic number of inner transition elements.
