Lewis diagram for NF3

Answer 1

Lewis dot diagrams represt the outer shell electrons covalently sharing between elements. For NF3 it would it would be pyramidal. Nitrogen has 5 outer shell electrons therefore you would attach the 3 fluorine atoms to the three outer shell electrons on the nitrogen. Then that leaves you with one non-bonding pair.

Answer 2

One nitrogen atom combines with three hydrogen atoms to form one molecule of ammonia (NH3). The nitrogen atom contributes 5 valence electrons to the molecule and the hydrogen atoms each contribute one valence electron. The new arrangement of valence electrons gives us four electron pairs arranged symmetrically around the nitrogen atom (forming the vertexes of a tetrahedron) and the hydrogen atoms are positioned at three of those four locations, each sharing one pair of electrons.

Answer 3

In a Lewis diagram for NF3, nitrogen is the central atom with three lone pairs and one bonded fluorine atom attached to it. Each fluorine atom has three lone pairs. The nitrogen atom has a lone pair and four total bonds (three with fluorine and one lone pair).

Answer 4

It is a pyramidal molecule where nitrogen is the central atom and surrounded by three fluoride atoms and an electron pair.
