Assertion : The maximum number of electrons in the shell with principal quantum number nis equal to 2n^(2) ?. Reason : Two electrons in an orbital have the same value of three quantum numbers n, l and m, but must have different spin quantum numbers.

Assertion : The transition of electrons n_(3) to n_(2) in H-atom will emit radiation of higher frequency than n_(4) to n_(3) . Reason : Principal shells n_(2) and n_(3) have lower energy than n_(4) .

The pronounced change from non-metallic to metallic behaviour and also increase in the basicity of oxides from nitrogen to bismuth in group 15 is principally due to increasing size of the atoms. The ionisation potential of nitrogen is very high on account of its small size. However, ionisation potential decreases regularly on descending the group. In all the group 15 elements, the number of unpaired electrons in the valence shell is:

Observe figure the electronic configuration of the second period elements of the group from 13-18 given below. Analyse table 3.1 and find whether there is any relation between the number of shells in an atom and the number of periods?

Statement 1 : The plots of probability density and radial probability function versus distance r from the nucleus for any particular orbital are not identical, Statement 2 : Probability density is psi^(2) whereas radial probability function represents probability of finding the electron in a shell of thickness dr.

Is there any relationship between the group number and the number of electrons present in the outermost shell? What is it?
