1. write the electronic configuration of these two elements.
2. which of these will be more electro negative and why?​

Answer 1

Answer:

Oxygen is the 2nd most electronegative element. When you examine a periodic table, you will find that (excluding the noble gases) the electronegativity values ...

Explanation:

Answer 2

Explanation:

Nitrogen :- 1s2 2s2 2p3

Phospshorus:- 1s2 2s2 2p6 3s2 3p3

Nitrogen is more electronegative than Phosphorus as while going down a grp electronegativity decreases
