E ANSWER element #1 hydrogen Z: Practice N- nitrogen 74F Clear Media That means the molecular formula for the compound formed by nitrogen and fluorin You do not have any ionic molecules in the table. But you can determine the chemical forr nonmetal element might make. To determine the chemical formula that a metal and nonm neutral ionic compound you must remember three important facts about ionic compounds argon . Most main group elements form only one typical ion. Because all the elements in this p elements, this fact will let you find the charge on the cation and anion. Each formula unit of an ionic compound must have a net charge of zero. This fact will le the cation and anion to find the empirical formula. Here is the completed table: +3 F Binary ionic compounds are always made of cations of the metal element and anions fact will tell you which element of each pair forms the cations, and which element forr .. element #2 chlorine helium .. fluorine E - = molecular neither ionic :F: 1 FIN F: molec
