Stable and Unstable Atoms

Overview

Atoms become chemically stable by losing or gaining to fill up their outermost electron shell to a configuration nearest to that of a noble gas. Atoms which attain noble gas configuration are non reactive in nature and are called stable atoms. Atoms which do not attain noble gas configuration are reactive in nature and are called unstable atoms.

After completing this module, you will be able to:

- Explain the conditions for an atom to be stable.
