E configuration of ions

Postby AMahadi » Sat Oct 19, 2019 4:42 pm

I am confused as to how to find the e- configuration of ions.

When an atom becomes an ion, it either loses its valence electrons or gains electrons to fill its outermost shell. In relation to the electron configuration, this means that the ion either has the same electron configuration as the atom but without the outermost subshell (the last segment of the electron configuration) or the outermost subshell is completely filled

So in lecture he used cation as an example. Cations are positive charged atoms because an e- is removed. The configuration is the same except a e- on the furthest/weakest orbital is removed. For anions you add an election to the furthest orbital.
