Question

general electronic configuration of representative elements
​

Answer 1

Answer:

The representative elements are those in which the distinguishing electron enter ans or p subshell. ... For representative elements the number of valence electrons is the same as the periodic group number, and the number needed to match the next noble-gas configuration is 8 minus the group number.

Answer 2

Answer:

The general configuration of s-block elements is ns1−ns2 and for p-block elements except noble gases is ns2np1−ns2np5. Thus combined for representative elements it is ns1−ns2p5.

The elements of s-block and p-block except noble gases are called representative elements.
