The Madelung rule gives the order:ġs < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s < 5f < 6d < 7p The s orbital holds a maximum of 2 electrons. The period or row numbers 1 through 7 are the energy levels of the elements. Alternatively, remember group 1 (alkali metals) and group 2 (alkaline earth metals) are s-block, groups 2 throuh 12 are the d-block, 13 to 18 are the p-block, and the two rows at the bottom of the table (the lanthanides and actinides) are f-block. Use the element blocks of the periodic table to find the highest electron orbital. If you don’t have a chart, you can still find the electron configuration. The electron configuration states where electrons are likely to be in an atom. Actual configurations have not been verified. Values denoted by an asterisk are predictions based on periodic table trends.

This table is available to download as a PDF to use as a study sheet. Look up the electronic configuration of that noble gas and include that value before the rest of the configuration. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. To save room, the configurations are in noble gas shorthand. This list of electron configurations of elements contains all the elements in increasing order of atomic number.
The electron configuration shows the distribution of electrons into subshells.
