General, Organic, and Biological Chemistry Copyright © 2010 Pearson Education, Inc. 8 Formation of Negative Ions In ionic compounds, nonmetals  achieve an octet arrangement  gain electrons  form negatively charged ions with 3 –, 2 –, or 1 – charges

General, Organic, and Biological Chemistry Copyright © 2010 Pearson Education, Inc. 9 Metals Form Positive Ions Metals form positive ions  by a loss of their valence electrons  with the electron configuration of the nearest noble gas  that have fewer electrons than protons Group 1A(1) metals ion 1+ Group 2A(2) metals ion 2+ Group 3A(3) metalsion 3+
