Section Name Experiment 13 Advance Study Assignment: The Geometrical Structure of Molecules You are asked by your instructor to construct a model of the NH,CI molecule. Being of a conservative nature, you proceed as directed in the section on Experimental Procedure. 1. First you need to find the number of valence electrons in NH,CL. For counting purposes with Lewis struc- the last digit in the tures, the number of valence electrons in an atom of a main group element is equal to group number of that element in the Periodic Table. N is in Group HÃs in Group ais in Group electrons. In NH,CI there is a total of 2. The model consists of balls and sticks. 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 the Cl atom? a. The electrons in the molecule are paired, and each stick represents a valence electron pair d. How many sticks do you need? Assemble a skeleton structure for the molecule, connecting the balls and sticks to make one unit. Use the rule that N atoms form three bonds, whereas Cl and H atoms usually form only one. Draw a sketch of th skeleton below: 3. 4. a. How many sticks did you need to make the skeleton structure? b. How many sticks are left over?
