Question

Li, F,N ( increasing order of electronegativitey)

Answer 1

Answer:

Li<C<N<Cl<F

trend of electronegativity -

it increases along period from left to right and decreases down the group.

Answer 2

Answer:

Increasing order of electronegativity -

Li < N < F

Explanation:

Fluorine is the most electronegative element because it has 5 electrons in it's 2P shell. The optimal electron configuration of the 2P orbital contains 6 electrons, so since Fluorine is so close to ideal electron configuration, the electrons are held very tightly to the nucleus. The high electronegativity of fluorine explains its small radius because the positive protons have a very strong attraction to the negative electrons, holding them closer to the nucleus than the bigger and less electronegative elements.

Lithium being a metal is more electropositive

It increases along period from left to right and decreases down the group.
