What is the maximum number of electrons that can occupy the 3d subshell?

Step 1: Understand what a subshell is. A subshell is a group of orbitals within an energy level where electrons can be found.
Step 2: Identify the principal quantum number (n) for the 3d subshell. For 3d, n = 3.
Step 3: Use the formula to find the maximum number of electrons in a subshell, which is 2n^2.
Step 4: Substitute n = 3 into the formula: 2(3^2).
Step 5: Calculate 3^2, which is 9.
Step 6: Multiply 9 by 2 to get 18. This means a maximum of 18 electrons can theoretically fit in a subshell with n = 3.
Step 7: However, the 3d subshell specifically can only hold a maximum of 10 electrons due to its orbital structure.
