  1. Electronic Configuration of Ions Nonmetallic elements form anions (-) • Hydrogen atoms gain one electron to form H- with a stable 1s2 electron configuration. • The other nonmetallic elements gain one, two, or three electrons to achieve a stable ns2np6 configuration. The group 17 nonmetals form -1 ions, the group 16 nonmetals form -2 ions, and the group 15 nonmetals form -3 ions. Metallic elements form cations. (You will only be able to predict some of the charges on these cations.) • Many elements lose one, two, or three electrons and achieve one or two of the stable electron configurations: 1s2, ns2np6, nd10, or nd10(n+1)s2.  http://www.mpcfaculty.net/mark_bishop/monatomic_ion_configurations.htm

When cations form, electrons are lost from the largest orbitals first. http://www.mpcfaculty.net/mark_bishop/monatomic_ion_configurations.htm
