Chemistry Question from JEE Main 2026 · 23 January, Shift 2

Identify the INCORRECT statements from the following: A. Notation $^{24}_{12}Mg$ represents $24$ protons and $12$ neutrons. B. Wavelength of a radiation of frequency $4.5 \times 10^{15} \, \text{s}^{-1}$ is $6.7 \times 10^{-8} \, \text{m}$. C. One radiation has wavelength $\lambda_1$ ($900 \, \text{nm}$) and energy $E_1$. Other radiation has wavelength $\lambda_2$ ($300 \, \text{nm}$) and energy $E_2$. $E_1 : E_2 = 3 : 1$. D. Number of photons of light of wavelength $2000 \, \text{pm}$ that provides $1 \, \text{J}$ of energy is $1.006 \times 10^{16}$.
