Question

Read the given statements carefully.
Statement-1: When an electron jumps from higher energy level to lower energy level, absorption of energy takes place.
Statement-2: Excited state provides instability to the electron. Thus, the electron tends to come back to its ground state to gain stability.
Now, choose the correct option.

• A. Both the statements are correct
• B. Both the statements are incorrect
• C. Only statement 1 is correct
• D. Only statement 2 is correct

Answer 1

The correct option is D Only statement 2 is correct

The lowest energy state of an atom is its ground state. When an electron in an atom has absorbed energy, it is said to be in an excited state. The excited state of an atom is unstable and therefore, the electron tends to come back to the lowest energy state, i.e., the stable state.
When an electron comes down from a higher energy level to a lower energy level, energy is released.
Hence, the correct answer is option (d).
