What is the significance of the 3d subshell in transition metals?

Back

The 3d subshell is involved in bonding and determines the chemical properties of transition metals.

Front

Define noble gas shorthand notation in electron configurations.

Back

Noble gas shorthand notation uses the electron configuration of the nearest noble gas to simplify the representation of an atom's electron configuration.
