The percentage of deuterated water (D2O and HDO) in normal water is approx. 0,015 %.

Normal water is made of H2O. That is: two hydrogen atoms and one oxygen atom. Heavy water is made of 2H2O (also known as D2O). That is: one deuterium atom and one oxygen atom. Deuterium is a variation of hydrogen which has a neutron in its nucleus (normal hydrogen has no neutrons). Do not confuse heavy water with H2O2, which is simply hydrogen peroxide.
This is the deuterium isotope, which has a nucleus of one proton and one neutron, whereas the predominant hydrogen isotope has just a proton. In natural water on earth, which is a compound of hydrogen and oxygen, H2O, there is a small proportion of water made from deuterium instead of normal hydrogen, this is often written as D2O. To make heavy water this compound is extracted, so you don't make the heavy water, you separate it out from natural water.
Heavy water is made with Deuterium which is an isotope of Hydrogen that has one Neutron in the atomic nucleus. Common hydrogen does not have any neutrons in the nucleus.This extra neutron makes the water heavier (twice the mass per atom) and more reactive.Heavy water is deuterium oxide. Ordinary water is Hydrogen Oxide.
Because heavy water is D2O and not H2O; the hydrogen atomic nucleus has only one proton, the deuterium has one proton and one neutron. Consequently the properties of the two isotopes are very different. The deuterated water is more dense than the normal water (1,1056 g/cm3 for D2O and 0,9982 g/cm3 for H2O.

Heavy water contain deuterium, a hydrogen isotope having one neutron.
The heavy water in a heavy water reactor is water where many of the regular hydrogen atoms (one proton and one electron) are replaced by heavy hydrogen (or deuterium) which has one proton, one electron, and one neutron. The addition of the neutron in the hydrogen atoms increases the mass (weight) of the water molecules and changes its chemical and physical properties making it useful in a heavy water reactor.Normal water is H2O or two hydrogen atoms and one oxygen atom. There is an isotope of hydrogen named deuterium. Deuterium is heavier than hydrogen but it's still hydrogen, so if one or more of the hydrogen atoms is replaced with deuterium it creates heavy water. So the water in a heavy water reactor is just water with deuterium atoms rather than ordinary hydrogen atoms. This is probably confusing but it is water and you could drink it without harm. But, don't drink a lot because the body is used to the lighter water.

Comets contain a small amount of so-called "heavy water" composed of equal parts hydrogen, oxygen, and deuterium. (Deuterium is an isotope of hydrogen with one extra neutron in its nucleus.) The chemical formula of heavy water is HDO; normal water is H2O.

Type your answer here... The hydrogen atoms in heavy water have a neutron in the nucleus, doubling the mass.
Water - There are three known Hydrogen variants of water. To understand this you have to realize that there are Three kinds of hydrogen: Hydrogen, Deuterium and Tritium. Each of these behave almost exactly like Hydrogen. They differ only on the nuclear level. Deuterium is heavier than Hydrogen and Tritium is heavier than Deuterium. Normal or common water (H2O)is composed of one Oxygen atom and two Hydrogen atoms. This is what you call hydrogen water. Heavy water or Deuterium Oxide (D2O) is the second of the three variants. Super heavy water, Tritiated water or Tritium Oxide (T20) is the third variant. It is radioactive and is incredibly rare. Natural drinking water is primarily Hydrogen based with a very small concentration of Deuterium based water.
It depends on the isotope. Ordinary hydrogen has no neutrons at all. However, deuterium is hydrogen with one neutron, and tritium is hydrogen with two neutrons. Deuterium is about twice as heavy as ordinary hydrogen, and tritium is three times as heavy, so hydrogen compounds in which some of the hydrogen is one or both of these heavier isotopes is correspondingly heavy. An example is heavy water. Normally, in formulas, the letters D and T are used instead of H to indicate deuterium and tritium. So, H has no neutrons.
