How are shells and subshells used in chemistry?

Shells and Subshells. Using the above you can work out the maximum number of electrons that can occupy a shell is 2n 2. Electrons are placed into available shells, starting with the lowest energy level. Each shell must be full before the next starts to fill. This model breaks down at the n=3 shell because each shell has subshells.

How are subshells related to the order they fill?

Note: subshells have different energy levels which can confuse the order they fill. Elements are grouped in blocks that refer to the subshell that contains the highest energy electron.

What does the table for the first four shells look like?

A complete table for the first four shells looks like: The number before each subshell specifies which shell it belongs to. As an example, Lithium has 3 electrons. 2 will first fill up the 1st shell in subshell 1s. The remaining electron will appear in the second shell in the 2s subshell.
