Vedclass · Answer

(C) Deuterium ($^2H$ or $D$) is an isotope of hydrogen with an atomic number of $1$ and a mass number of $2$. It consists of $1$ proton $(p^+)$,$1$ neutron $(n)$,and $1$ electron $(e^-)$. Option $A$ is correct as it is an isotope. Option $B$ is correct as it lists the correct subatomic particles. Option $D$ is correct as $D_2O$ is indeed called heavy water. Option $C$ is incorrect because it omits the electron $(e^-)$,which is essential for the neutral atom of deuterium.
