Question

Arrange the following elements in order of their increasing electronegativity P,O, and N.

Answer 1

Answer:

Oxygen (highest)

Nitrogen (lower than O, higher than phosphorus)

Phosphorus (lowest)

Explanation:

O and N are in the same period. O has one more proton than N, both have valence electrons in the n=2 shell.

P is in the third shell. Its valence electrons are in the n=3 shell (P atoms are bigger than N atoms).
