Anion Formation
- Anions are the negative ions formed when an atom gains one or more electrons.
- When nonmetals gain electrons, they gain as much as they need to
fullfill their outermost principal energy level with eight electrons.
- Outer electron configurations are constant
within a group, so the pattern of atom
formation repeats itself.
- The outermost prinicpal level is usually an octet.
