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.
Phosphorus has 3 electrons in the 4p sublevel.
M1 = -1
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
l = 1
When the 3d orbitals are completely filled, the new electrons will enter the 4s orbital before filling the 3d orbitals. This is because the 4s orbital has a lower energy level than the 3d orbitals, making it the first choice for accommodating additional electrons.
Phosphorus has 3 electrons in 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 element in Period 4 that has two electrons in the p sublevel is germanium (Ge). It has the atomic number 32 and is located in group 14 of the periodic table. In its electron configuration, germanium has the outermost electrons in the 4s and 4p sublevels, with the 4p sublevel containing two electrons.
Selenium or Se
The second quantum number, also known as the azimuthal or angular momentum quantum number (l), describes the shape of an electron's orbital. For the 4p energy sublevel, the value of l is 1, as p orbitals correspond to l = 1. Therefore, for one of the electrons in the 4p sublevel of bromine, the second quantum number is 1.
M1 = -1
ms -1/2
ms -1/2
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
ms=-1/2
The next highest energy atomic sublevel after 4p is the 5s sublevel. In the electron configuration of an atom, energy levels increase with increasing principal quantum number (n), so the 5s sublevel is higher in energy than the 4p sublevel.
l = 1
