what is the covalent bond for Nitogen and Fluride

Question

WHAT IS THE Covalent bond for nitrogen and flouride with the work with 

Answer 1

N and F can (reluctantly) form the molecule NF3. All bonds are single polar covalent.

Surprisingly, it is not a very reactive molecule, though it has specific uses in semiconductor etching. It's also a potent greenhouse-effect gas.

An analog is NCl3, formed by reaction of excess bleach with a little ammonia. (This reaction proceeds vigorously! NCl3 is a nerve gas; also likely to make lower-chlorinated amount amines, very odorous, very toxic.)

Really, tutors, you can Google molecules to check them out, before declaring them DOA ...

Answer 2

Can you clarify the question?

Answer 3

I am guessing that this is a Lewis Structure question... There will be a double bond between N and F. One of F's valence electrons is "donated" to N, (I think the convention is to draw an "X" through the F  electron and an arrow leading to the position of N to which it was moved) then you are able to represent the second bond.

As Dick B. commented, the formation of an NF molecule is highly unlikely due to the electronegativity of Fluorine. So, this structure is strictly hypothetical.
