Attain a full outer shell to become more stable - 9Dot- Cross model
- 10Ball and Stick model
- 11Allotropeeach of two or more different physical forms in which an element can exist.
- 12Isotopethe same element with different numbers of neutrons in the nucleus and therefore a different atomic mass. Some isotopes can be radioactive.
