SUMMARY
The maximum number of electrons that can occupy an orbital is determined by the principal quantum number (n). For n=1, the only subshell is the 1s, which can hold a maximum of 2 electrons. For n=2, the subshells include 2s and 2p, allowing for a total of 8 electrons (2 in 2s and 6 in 2p). The calculation is based on the formula 2n², confirming that for n=1, the result is 2, and for n=2, the result is 8.
