Document Summary

Chapter 8 names and formulas for ionic compounds. Covalent: sharing of valence electrons between atoms, formed between nonmetals. Elements on either side of the dividing line are metalloids except for al. Elements to left of staircase metalloids are metals. Elements to right of staircase metalloids are non-metals. Cations are positive ions while anions are negative ions. The simplest ratio of ions represented in an ionic compound. Bond formed via transfer of valence electrons to form an anion and a cation, usually resulting in the filled octet shells of both the cation and the anion. A one-atom ion such as 2+ charged mg cation or a 1- charged br anion. For the a group elements, the charge is: Group 5a: -3 (only for things to the right of staircase) Group 6a: -2 (only for things to the right of staircase) Group 7a: -1 (only for things to the right of staircase)
