Deuterium
is a hydrogen isotope with a nucleus containing a neutron and a proton; the nucleus of a protium (normal hydrogen) atom consists of just a proton. The additional neutron makes a deuterium atom roughly twice as heavy as a protium atom.

Heavy Water (D
2
O) or
deuterium oxide
is made up of two atoms of deuterium and one atom of oxygen. Deuterium is a stable isotope of hydrogen with double the mass of hydrogen due to presence of an extra neutron in its nucleus. Deuterium is present in hydrogen and hydrogen bearing compounds like water, hydrocarbons, etc.

How is hydrogen in heavy water different from hydrogen in normal water?
Heavy water is water that contains heavy hydrogen – also known as deuterium – in place of regular hydrogen. … Deuterium is different than the hydrogen that usually
occurs in water
—known as protium, since each atom of deuterium contains a proton and a neutron, while more commonly occurring hydrogen contains only a proton.
Which isotope of hydrogen is radioactive?
Tritium (13H or T)

is a hydrogen isotope consisting of one proton, one neutron and one electron. It has major applications in nuclear magnetic resonance studies.
Is tritium heavy water?
In its pure form it may be called tritium oxide (T
2
O or
3
H
2
O) or
super-heavy water
. … It is also used as a tracer for water transport studies in life-science research.
Which is heavier deuterium or tritium?
Deuterium
and tritium are isotopes of hydrogen, the most abundant element in the universe. Whereas all isotopes of hydrogen have one proton, deuterium also has one neutron and tritium has two neutrons, so their ion masses are heavier than protium, the isotope of hydrogen with no neutrons.
Which of following is heavy water?
As we have seen
deuterium
is a heavier isotope than hydrogen that is why this similar looking water molecule is known as heavy water. It is also called deuterium oxide just like water is called hydrogen oxide.
What are isotopes write 3 isotopes of hydrogen?
There are three isotopes of the element hydrogen:
hydrogen, deuterium, and tritium
. How do we distinguish between them? They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons.
What is d2 in chemistry?
Deuterium
is an isotope of hydrogen but it is chemically identical. It is a colorless, odorless gas. It is easily ignited.
Which of the following is correct for heavy water?
Answer:(c) It is formed by the combination of heavier isotope of hydrogen with oxygen is the correct answer. Explanation: Heavy water is
deuterium oxide (D2O)
.
How does heavy water reacts with AlCl3?
Since Al3+ is in water, six molecules of H2O coordinates to it and form the complex [Al(H2O)6]3+. The bond between
oxygen and aluminum becomes stronger
and bond between hydrogen and oxygen is weaken thus breaks off and forms H+ which is the reason for acidity when AlCl3 dissolves in water.
How does heavy water react with SO3?
– Deuterium oxide (D2O) is called heavy water. … – Heavy water (D2O) reacts with sulphur trioxide
to form deuterosulphuric acid
. D2O + SO3 –> D2SO4. Hope this solved your query.
How does heavy water reacts with Al4C3?
It reacts with heavy water to form aluminium hydroxide nd methane, that is ,
Al4C3 + H20 = AL(OH)3 + CH4

, which is used to observe the magnetic fields around the nuclei of atoms. Isotopologues of many organic compounds are prepared with the help of deuterium oxide. Heavy water is often used instead of normal water in IR (infrared) spectroscopy.
Can you drink heavy water?
While heavy water isn’t radioactive,
it’s not entirely safe to drink
. … Basically, the mass difference slows biochemical reactions that use water. Also, deuterium forms stronger hydrogen bonds than protium, resulting in a different reactivity. You can drink a glass of heavy water and won’t suffer any ill effects.
Which type of reactor is called Candu type reactor Mcq?
The CANDU (Canada Deuterium Uranium) is
