You are asked by your instructor to construct a model of the NH_2Cl molecule. Being of a conservative nature, you proceed as directed in the section on Experimental Procedure. First you need to find the number of valence electrons in NH_2Cl_2. 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...
