the p subshell has 3 orbitals. Each Orbital can hold 2 electrons with opposite spins. therefore the p subshell can hold a maximum of 6 electrons.
2 electrons can occupy a 4s subshell (K, Ca)
The formula for how many electrons are in a given shell is: 2n2 where n= # of shells. You enter 4 in for "n" and you will get 32 electrons.

After the 3d sublevel is filled, additional electrons will occupy the 4p orbitals, for a total of 6 electrons in the 4p sublevel.
l = 1
M1 = -1
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
The 4s orbital falls in a slightly lower energy level than the 3d orbital when it is empty so it will fill with electrons first, but when it is full of electrons it rises to be above the 3d one so that it will lose electrons first as well.
After the 3d sublevel is filled, additional electrons will occupy the 4p orbitals, for a total of 6 electrons in the 4p sublevel.
Selenium or Se
l = 1
The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.

The maximum number of electrons in the 2p sublevel is 6. The p sublevel has three orbitals, each of which can take two electrons.
The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.
