Question

nitrogen atomic number 7 and phosphorus atomic number 15 belong to group 15 of the periodic table write the electronic configuration and those two elements which of the it will be more electrolysis?why​

Answer 1

Answer:

Atomic number of nitrogen is 7 and its electronic configuration is as follows. Atomic number of phosphorous is 15 and its electronic configuration is as follows. Since both nitrogen and phosphorous are same group elements. Also, it is known that electronegativity decreases on moving down a group.

Explanation:

Answer 2

Answer:

The electronic configurations of the two elements are nitrogen (Z = 7) 2, 5; Phosphorus (Z = 15) 2,8, 5.

Since the size of nitrogen is small as compared to phosphorus, it has a greater tendency to take up electrons. It is therefore, more electro-negative than phosphorus.
