In s.p.d.f. notation, the first number is the main energy level (quantum shell), also known as n. In this case, n = 4, hence this is the 4th energy level we are talking about.
The letter in the middle is the orbital in that energy level. There are s-orbitals, p-orbitals, d-orbitals and f-orbitals. Here we are talking about the p-orbitals of the 4th main energy level (i.e. the dumbbell shaped orbitals).
The final number of the notation is the number of electrons occupying that orbital of that energy level. All s-orbitals can only hold up to 2 electrons, p-orbitals can hold up to 6 electrons, d-orbitals up to 10, and so on. The 3 in "4p3" is hence referring to the 3 electrons in the p-orbital of the 4th energy level.
I hope that helps! :)

The minimum salary for pay grade 4p3 at Stanford is $58,070. The maximum salary for this grade is $92,930
4P3= 4!/(4-3)! = 4!/1! = 4!/1 = 24/1 = 24

Arsenic's atomic number is 33. That means neutral arsenic has 33 protons and 33 electrons. Thus, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3.
It's stable with 42 neutrons 33 protons and electrons although normally it has 3 extra electrons but it's stable
Short answer: [Ar] 3d10 4s2 4p3 OR 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3
