Question

how many electrons can fit in a full d subshell? *
2
6
10
14

Explanation:

In atomic structure (a topic in Chemistry, part of Natural Science), the number of orbitals in a subshell is determined by the angular momentum quantum number (\(l\)). For a d subshell, \(l = 2\). The number of orbitals in a subshell is \(2l + 1\), so for \(l = 2\), the number of orbitals is \(2(2)+ 1=5\) orbitals. Each orbital can hold a maximum of 2 electrons (due to the Pauli exclusion principle, which states that no two electrons in an atom can have the same set of four quantum numbers). So, to find the number of electrons in a full d subshell, we multiply the number of orbitals by 2: \(5\times2 = 10\) electrons.
