Question

nitrogen and phosphorus belong to group 15 of the periodic table. write the electronic configuration of these two elements. which of them will be more electronegative and why?

Answer 1

Nitrogen - 2,5

Phosphorus - 2,8,5

Answer 2

Answer: Electronic configuration:

$N:7:1s^22s^22p^3$

$O:8:1s^22s^22p^4$

Oxygen is more electronegative as it can easily gain electrons to attain stable noble gas configuration.

Explanation: Nitrogen is an element with atomic number 7 has 7 electrons which are arranged in energy levels arranged in increasing order of energies as shown below:

$N:7:1s^22s^22p^3$

Oxygen is an element with atomic number 8 has 8 electrons which are arranged in energy levels arranged in increasing order of energies as shown below:

$O:8:1s^22s^22p^4$

Electroneagtivity is the tendency of an element to attract the shared pair opf electrons towards itself.

Oxygen is more electronegative as it can easily accept electrons as it only needs two electrons to complete its octet.

$O^{2-}:10:1s^22s^22p^6$
