STUDENT STUDY GUIDE FOR 8TH GRADE CHEMISTRY

Atoms with 5 or more valence electrons can gain electrons to have a full outer shell. If chlorine gains an electron, it will have 8 electrons in the outer shell, and it will have a stable electron configuration. Chlorine is neutral to begin with, so if it gains an electron, it will have a net charge of -1. The chloride ion has a charge of -1. ................
