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:

Nitrogen-2,5

phosphrus-2,8,5

Explanation:

Answer 2

$\huge\tt\blue{Answer→}$

Atomic number of Nitrogen is 7 hence Electronic configuration of Nitrogen is 1s2 2s2 2p3

Atomic number of Nitrogen is 15 hence Electronic configuration of Phosphorous is 1s2 2s2 2p6 3s2 3p3

On moving down a group in the periodic table, the number of shell increases. Due to this, valence electrons move away from the electrons and the effective nuclear charge decreases. This causes the decrease in the tendency to attract electron and hence electro negativity decreases. Because of all these reasons Nitrogen is more electronegative than phosphorus.
