The maximum number of electrons in a subshell is given by the expression

1. 4l − 2
2. 4l + 2
3. 2l + 2
4. 2n2

Correct answer: 4l + 2

Solution

The maximum number of electrons in a subshell is determined by the formula 2(2l + 1), which simplifies to 4l + 2. Here, 'l' is the azimuthal quantum number.
