Correct answer: C. Metastable state
- A. Ground state
- B. Ionized state
- C. Metastable state
- D. Ordinary excited state
Explanation
The excited state that persists for an unusually longer period of time is called a metastable state. In a metastable state, the atom or molecule remains in an excited state for a relatively extended duration before returning to its ground state. This occurs due to certain quantum mechanical restrictions that impede the immediate transition to the ground state.

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.
