Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to Group 15 of the Periodic Table. Write the electronic configuration of these two elements. Which of these will be more electronegative ? Why ? |
|
Answer» SOLUTION :Nitrogen with atomic NUMBER 7 has got 7 electrons with electronic configuration 2, 5 i.e., 2 electrons in K-shell and 5 electrons in L-shell. Phosphorus with atomic number 15 has got 15 electrons with electronic configuration 2, 8, 5 i.e., 2 electrons in K-shell, 8 electrons in L-shell and 5 electrons in M-shell. Non-metallic character decreases as we MOVE down the group. THEREFORE, nitrogen will be more ELECTRONEGATIVE than phosphorus. |
