The correct Answer is:
To determine which metal imparts a brick red color to the flame, we can analyze the options provided: beryllium, magnesium, calcium, and barium. ### Step-by-Step Solution: 1. **Understanding Flame Colors**: - Different metals produce characteristic colors when heated in a flame due to the excitation of their electrons. When these electrons return to their ground state, they emit light of specific wavelengths, which corresponds to different colors. 2. **Analyzing the Options**: - **Beryllium (Be)**: Beryllium does not impart any color to the flame. This is because it has a small atomic size and a high effective nuclear charge, which means its electrons are held tightly and do not get excited easily. - **Magnesium (Mg)**: Similar to beryllium, magnesium also does not impart any color to the flame for the same reasons: small size and high effective nuclear charge. - **Calcium (Ca)**: Calcium is known to impart a brick red color to the flame. This is due to the excitation of its electrons, which can easily absorb energy from the flame and emit light when they return to the ground state. - **Barium (Ba)**: While barium does impart a color to the flame, it is typically greenish-yellow, not brick red. 3. **Conclusion**: - Among the options, calcium is the only metal that imparts a brick red color to the flame. Therefore, the correct answer is calcium. ### Final Answer: The metal which imparts brick red color to flame is **Calcium (Ca)**. ---
