Question

In a sodium crystal, the difference between two consecutive energy levels is approximately -

• A. ${10}^{-10}\text{eV}$
• B. ${10}^{-75}\text{eV}$
• C. ${10}^{-23}\text{eV}$
• D. ${10}^{-50}\text{eV}$

Answer 1

The correct option is C ${10}^{-23}\text{eV}$

In a sodium crystal, the difference between two consecutive energy levels is approximately ${10}^{-23}\text{eV}$.

Hence, option $\left(C\right)$ is the correct answer.
