Question

nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of the periodic table
a) write the electronic configuration of these two elements and
b) which of these will be more electronegative ? why?​

Answer 1

Answer:

nitrogen= 2,5

Phosphorus=2,8,5

nitrogen is more electronegative because electeonegativitiy increases from left to right and decreasing on moving down to grp

thanks for asking I hope you understand

Answer 2

Answer:

a)

Nitrogen electronic configuration is 2,5

phosphorous atomic number is 2,8,5

b)

Nitrogen and Phosphorus are the elements of same group i.e group 15. ... The non- metallic character of any element is characterized by its tendency to lose electron i.e electronegativity. Hence, electronegativity decreases on going from top to bottom in a group. Therefore, Nitrogen is more electronegative than Phosphorus.
