Question

The incorrect statement about deuterium is :

• A. it is an isotope of hydrogen
• B. it contains $\left[\right(1e^{-})+(1p^{+})+(1\left(n\right)]$
• C. it contains $\left[\right(1p^{+})+(1\left(n\right)]$
• D. $D_{2}O$ is called heavy water

Answer 1

Answer: (C)

it contains $\left[\right(1p^{+})+(1\left(n\right)]$

The statement C is the false statement.

(A) It is an isotope of hydrogen. It has atomic number 1 and mass number 2.

(B) It contains $\left[\right(1e^{-})+(1p^{+})+(1\left(n\right)]$

(C) Its nucleus contains only $\left[\right(1p^{+})+(1\left(n\right)]$

(D) Dueterium oxide $D_{2}O$ is called the heavy water.
