Final answer:
The total number of electrons that can be accommodated in all orbitals with principal quantum number 2 and azimuthal quantum number 1 is 6 electrons, as each of the three p orbitals in the 2p subshell can hold two electrons with opposite spins.
The correct option is (c) 6 electrons
Step-by-step explanation:
The question pertains to the total number of electrons that can be accommodated in all orbitals having a principal quantum number 2 (n = 2) and an azimuthal quantum number 1 (l = 1).
This defines a 2p subshell, which, according to the quantum model, can have three orbitals (m = -1, 0, +1). Applying the Pauli exclusion principle, each orbital can hold a maximum of two electrons with opposite spins. Therefore, the total number of electrons in a 2p subshell is 3 orbitals × 2 electrons per orbital = 6 electrons. Thus, the correct option is (c) 6 electrons
