Quizplus · Accepted Answer

The number of subshells in a shell is equal to its principal quantum number (n). So, in this case, n=3 means there are 3 subshells. The number of orbitals in a subshell is given by 2l+1, where l is the angular momentum quantum number. The maximum value of l in a subshell is n-1, so in this case, the possible values of l are 0, 1, and 2. This gives us a total of 2(0)+1 + 2(1)+1 + 2(2)+1 = 1+3+5 = 9 orbitals in the shell. Each orbital can hold a maximum of 2 electrons, so the shell can hold up to 2(9) = 18 electrons. Therefore, the correct answer is D) 3;9;18.
