Question

how many electrons can the d sublevel hold? 14 10 2

Explanation:

Step1: Recall electron - subshell capacity formula

The formula for the number of electrons in a subshell is \(2(2l + 1)\), where \(l\) is the azimuthal quantum number. For the \(d\) sub - level, \(l = 2\).

Step2: Substitute \(l = 2\) into the formula

$$

Another way: The \(d\) sub - level has \(5\) orbitals (\(m_l=- 2,-1,0,1,2\)). Since each orbital can hold a maximum of \(2\) electrons, \(5\times2=10\)

Answer:
