The arrow goes through 1s first, then 2s, then 2p & 3s, then 3p & 4s, then 3d, 4p, & 5s, and so on. Some people find it easier to use the periodic table as the “road map”: As you move through the elements in order by atomic number, you are moving through the sub-levels from lowest to highest energy.

The letters s, p, d, f (and some more) come from the angular momentum quantum number l (l can vary between 0 and n-1). l says something about the shape and number of the orbitals.

Aufbau Principle - electrons fill orbitals starting at the lowest available energy state before filling higher states (1s before 2s).

Fördelning av elektroner över elektriska nivåer. Vad är

4 corresponds to 4s 4p 4d 4f. Thus 1s 2s 2p 3s 3p 3d the next will be 4s…. As an example, the ground state configuration of the sodium atom is 1s 2 2s 2 2p 6 3s 1, as deduced from the Aufbau principle (see below). The first excited state is obtained by promoting a 3s electron to the 3p orbital, to obtain the 1s 2 2s 2 2p 6 3p 1 configuration, abbreviated as the 3p level. The numbers 1, 2, 3 etc come from the principal quantum number n. The letters s, p, d, f (and some more) come from the angular momentum quantum number l (l can vary between 0 and n-1).

2p will be filled next, with the maximum of 6 electrons. Continue until no any electrons left. Example: write electron configuration for titanium (Ti) atom. Look at the periodic table, atomic number is 22. Explicit 2p to 1s Decay Rate Starting from the summary equation for electric dipole transitions, above, we specialize to the 2p to 1s decay, 9.
