Maximum number of electrons in a subshell of an atom is determined by the following:

1. 2l + 1
2. 4l - 2
3. 2n²
4. 4l + 2

Correct answer: 4l + 2

Solution

The maximum number of electrons in a subshell is given by the formula 2(2l + 1), which simplifies to 4l + 2. This accounts for the two possible spin states of each orbital in the subshell.
