What is the maximum number of electrons that can occupy the 3d subshell of an atom?
Correct answer: C. 10
- A. 2
- B. 6
- C. 10
- D. 14
Explanation
The 3d subshell has 5 orbitals (d subshell: l = 2, m_l = -2, -1, 0, +1, +2), each holding 2 electrons. Thus, maximum electrons = 5 × 2 = 10.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
