Prelab Assignment You are asked by your instructor to draw the Lewis structure of the NHCI molecule. Being of a conservative nature, you proceed as directed in the Procedure section. 1. First, find the number of valence electrons in NHECI. For counting purposes with Lewis structures, the number of valence electrons in an atom of a main group clement is equal to the last digit in the group number of that element in the Periodic Table. N is in Group...
Experiment 5: Nomenclature of Chemical Compounds and Formula Writing Experiment NOMENCLATURE OF CHEMICAL COMPOUNDS AND FORMULA WRITING The After Thought 1. Consider the elements in period or row 3 of the Periodic Table. Each element is expected to form a simple ion as atoms of that element gain or lose electrons. Write the charge expected for each of these elements in the corresponding box below. Group 1 III IV V VI VII NU 2. Circle either ionic (l) or molecular...
