The correct Answer is:
To determine the maximum number of electrons that can occupy the s, p, and d subshells, we can follow these steps: ### Step 1: Understand the structure of subshells - Each subshell consists of a certain number of orbitals. The number of orbitals in each subshell is defined as follows: - **s subshell**: 1 orbital - **p subshell**: 3 orbitals - **d subshell**: 5 orbitals ### Step 2: Calculate the maximum number of electrons for each subshell - The maximum number of electrons that can occupy an orbital is 2 (due to the Pauli exclusion principle). Therefore, we can calculate the maximum number of electrons for each subshell by multiplying the number of orbitals by 2. #### For the s subshell: - Number of orbitals = 1 - Maximum number of electrons = 1 orbital × 2 electrons/orbital = 2 electrons #### For the p subshell: - Number of orbitals = 3 - Maximum number of electrons = 3 orbitals × 2 electrons/orbital = 6 electrons #### For the d subshell: - Number of orbitals = 5 - Maximum number of electrons = 5 orbitals × 2 electrons/orbital = 10 electrons ### Step 3: Summarize the results - The maximum number of electrons in: - **s subshell**: 2 electrons - **p subshell**: 6 electrons - **d subshell**: 10 electrons ### Final Answer: - The maximum number of electrons in s, p, and d subshells are 2, 6, and 10, respectively. ---
