The statement that is not correct for the periodic classification of elements is
- the properties of elements are the periodic functions of their atomic numbers
- non-metallic elements are lesser in number than metallic elements
- the first ionisation energies of elements along a period do not vary in a regular manner with increase in atomic number
- for transition elements the d-subsells are filled with electrons monotonically with increase in atomic number.
Answer
(D) for transition elements the d -subsells are filled with electrons monotonically with increase in atomic number.
