Question
Which of the following metals burn with brick red flame?A. PbB. CaC. NaD. Mg
Solution
The metal that burns with a brick red flame is Calcium (Ca). So, the correct answer is B. Ca.
Here's a step-by-step explanation:
-
Each metal has a characteristic color that it gives off when burned. This is due to the energy levels in the atoms of the metal getting excited and then releasing energy as light when they return to their ground state.
-
Lead (Pb) burns with a blue-white flame, Sodium (Na) burns with a bright yellow flame, and Magnesium (Mg) burns with an intense white flame.
-
Calcium (Ca), however, burns with a brick red flame. This is a characteristic property of calcium and is often used in "flame tests" in the lab to identify the presence of calcium.
