two and both must be of opposite spin to each other
The electrons in beryllium occupy a total of four orbitals. Beryllium has 4 electrons, which fill the 1s, 2s, and 2p orbitals.
In an atom with seven electrons, such as nitrogen (atomic number 7), the electron configuration is 1s² 2s² 2p³. Of these seven electrons, three occupy the P orbitals (2p³), while the other four fill the 1s and 2s orbitals. Therefore, in this case, three of the seven electrons occupy P orbitals.

17. The electronic configuration of bromine is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 4p5

Fluorine has 9 electrons, which occupy 2s and 2p orbitals. Therefore, there are a total of three orbitals in fluorine (one 2s orbital and two 2p orbitals).
Three degenerate orbitals are needed to contain seven electrons with five unpaired. Two electrons will occupy two of the degenerate orbitals, while the remaining five electrons, each with one electron, will occupy the third degenerate orbital.
5 electrons in p orbitals in the outer shell. Cl has an electronic configuration of [Ne] 3s2, 3p5 In level 2 there a further 6 electrons in p orbitals making 11 electrons in total occupying p orbitals
A set of p type orbitals can hold a maximum of 6 electrons, with each p orbital able to hold a maximum of 2 electrons. This is because there are three p orbitals (px, py, pz) available for electrons to occupy in a given energy level.
Arsenic has three electrons occupying the three 4p orbitals in its valence shell. Hund's first rule tells us that they will each occupy separate orbitals before they start to pair up. So there are three half-filled orbitals in an arsenic atom.
No. Electrons are fermions, meaning they cannot share the same set of four quantum numbers. Usually when we say "orbital" we only mean the first three, so there is room for two electrons in an orbital (corresponding to the two possible ms values).
Every orbital is different. 2 can occupy the first orbital then 8 can occupy mostly the rest. When you start getting really low on the periodic table orbitals start holding 16, but not till u get really low
