Why is deuterium 2H1 sometimes called heavy hydrogen?
A
It has extra nucleus
B
It has extra proton
C
It has extra electron
D
It has extra neutron
Explanation: 

Detailed explanation-1: -Deuterium contains one proton and one neutron. Thus, the mass of deuterium is two. Thus, its mass is twice of the hydrogen atom. Hence, it is called heavy hydrogen.

Detailed explanation-2: -deuterium, (D, or 2H), also called heavy hydrogen, isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton).

Detailed explanation-3: -Deuterium, an isotope of hydrogen given by 21H, is also known as heavy hydrogen because of the extra neutron in the atomic nucleus.

Detailed explanation-4: -Deuterium (or hydrogen-2, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1). The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons in the nucleus.
