Here's how to understand it:
* The numbers (1, 2, 3, etc.) represent the energy levels or electron shells.
* The letters (s, p, d, f) represent the subshells within each energy level.
* The superscripts indicate the number of electrons in each subshell.
Important Note: Mendelevium is a synthetic element, meaning it doesn't occur naturally. Its electron configuration is based on its position in the periodic table and the rules of filling orbitals.
