Electronic configuration of an element is:

The third period (n = 3) begins at sodium with addition of first electron to

Before the 4p orbital is filled, filling up of 3d orbitals becomes energetically favourable and there are 3d transition series of elements. This starts from scandium (Z = 21) which has the outermost electronic configuration of.

Maximum number of electrons occupied by s,p and d orbitlas are:

s-block elements comprise of

All the orbitals in the valence shell of the noble gases

d-Block Elements are characterized by the
