Document Summary

Ionic compounds (frequently metal + nonmetal): metals conduct electricity because (charged) electrons flow easily from metal atom to metal atom. Melt (not dissolve!) salt (nacl) by heating it: the (hot) liquid conducts electricity, dissolve a salt in water and the solution conducts electricity, nacl is made of ions that can move in the melt and in solution. For each of the following atoms or ions, give the number of protons, and the number of electrons in one particle: an fe atom; protons: 26. Electron:26: an fe3+ ion; protons: 26 protons, electrons: 23, an n3- ion; protons:7, electron: 10. When a metal atom loses electrons to become an ion, it becomes a (positively charged) cation (is attracted to a negative cathode) When a nonmetal atom gain electron to become an ion, it becomes a (negatively charged) anion (is attracted to a negative anode) Use the periodic table to figure out formulas of ionic compounds and the charges on ions.
