1. First you need to find the number pf valence electrons on NH2Cl for counting purposes with lewis structures the number of valence electrons in an atom of a main group element is equal to the last digit in the group number of that element of that element in the periodic table. N is in group__ h is in group __ Cl is in group___ in NH2Cl there is a total of __ valence electrons.

2. the model consists of balls and sticks

a. how many holes should be in the ball you select for the N atom?

b. how many holes should be in the ball you select for the H atoms?

c. How many holes should be in the ball you select for Cl atom?

The electrons in the molecule are pairs and each stick represents a valence electron pair.

d. how many sticks do you need?

3. Assemble a skeleton structure for the molecule, connecting the balls and sticksk to make one unit. use the rule that N atoms form three bonds whereas Cl and H atoms usualy form only one. draw a sketch of the skeleton below.

4. a.How many sticks did you need to make the skeleton structure

b. how many sticks are left over?
