Question

how many electrons can the d sublevel hold? 4 8 10 2

Explanation:

Step1: Determine the number of orbitals in d sub - level

The d sub - level has \(l = 2\). The number of orbitals in a sub - level is given by \(2l + 1\). For \(l=2\), the number of orbitals \(n=2\times2 + 1=5\).

Step2: Calculate the number of electrons

Each orbital can hold a maximum of 2 electrons. So the number of electrons in the d sub - level is \(2\times5 = 10\).

Answer:

10
