Chapters 7&8 Gauge Sheet 7.1- Ions To find the number of valence electrons in an atom of a representative element‚ simply look at its group number. Atoms of metals tend to lose their valence electrons‚ leaving a complete octet in the next-lowest energy level. Atoms of some non-metals tend to gain electrons or to share with another non-metal to achieve a complete octet. The gain of negatively charged electrons by a neutral atom produces an anion. 7.2- Ionic Bonds and Ionic Compounds Although
