I am confused on what number means what during an electronic configuration.

So, the first number is the energy level and the row number ( and d is one behind)?

The letter tells what orbital the electron is in?

The number tells how many electrons are in the orbitals and whether they are paired or parallel?

Based on my understanding of this topic, I think the first number is indicative of the energy level/shell the electrons occupy. (In the s- and p- blocks this number corresponds with the number of the row, but the 4s level fills up before the 3d level, and so on for each row.) Then, the letter represents the subshell/orbital the electrons occupy, and the superscript is the number of electrons in that orbital.
