Question

A molecule of ammonia has the formula nh3 draw . electron dot structure for this molecule showing how all gour atoms achieve noble gas configaration will the molecule have single double or triple bond

Answer 1

Each hydrogen atom give one electron and get one from Nitrogen. Nitrogen has a lone pair of electrons and three bond pairs. All are single bonds. One lone pair giving it a trigonal pyramidal shape

Answer 2

Answer: The atoms have single bond between them.

Explanation:

Electron-dot structure is defined as the arrangement of outermost electrons around the atom. The electrons are represented as dots.

We are given:

A chemical compound having formula $NH_3$

We know that nitrogen has '5' valence electrons and hydrogen has '1' valence electron.

So, the total number of valence electrons in $NH_3$ = 5 + 3(1) = 8

In $NH_3$, one electron each of 3 hydrogen combine with 3 electrons of nitrogen and 1 pair electrons of nitrogen is left as a lone pair. This means that the given compound has 3 bonding pairs and 1 lone pair.

Nitrogen and hydrogen atoms combine by forming single bond between them.

The electron dot structure is given below.
