Question

How is electronic configuration of element related to its position in modern periodic table give example..why is nitrogen more electronegative then phosphorus​

Answer 1

Answer:

Electronic configuration of elements is related to its position in periodic table by following:

1) As we move left to right in period number of valence electrons increases from 0 to 4 and decrease from 4 to 0.

2) As we move down across period number of shells or orbit increases.

Nitrogen is more electronegative than Phosphorus because it has to gain only 1 electron to achieve it's nobel gas configuration.
