Deuteron, nucleus of deuterium (heavy hydrogen) that consists of one proton and one neutron. Deuterons are formed chiefly by ionizing deuterium (stripping the single electron away from the atom) and are used as projectiles to produce nuclear reactions after accumulating high energies in particle accelerators.

Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.

(i)Deuteron is an isotope of hydrogen. It is represented as 1H2. Therefore, it has one electron in it which means q=1. And it has mass m=2. (ii)An α-particle is simply a helium molecule.

Extracting this deuterium from seawater is a simple and well proven industrial process. “Heavy water”, or D2O (water in which deuterium substitutes for hydrogen), is first separated from regular water by chemical exchange processes, and is then submitted to electrolysis in order to obtain deuterium gas.

Deuterium has a natural abundance in Earth’s oceans of about one atom in 6420 of hydrogen. Thus deuterium accounts for approximately 0.0156% (0.0312% by mass) of all the naturally occurring hydrogen in the oceans, while protium accounts for more than 99.98%.

Highly flammable. Deuterium, like hydrogen, is a reducing agent; reacts readily with oxidizing agents.

Since only about one water molecule in 20 million naturally contains deuterium—which adds up to about five grams of natural heavy water in your body and is harmless—you don’t really need to worry about heavy water poisoning.

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. For example, when a proton and neutron combine to form deuterium, the reaction can be written 1n + 1H Æ 2H + g.

Because heavy water makes eukaryotic cell division impossible due to its impact on the mitotic spindle, plant seeds will not germinate when only fed heavy water. Plants will live but will be unable to grow or regenerate lost cells.

Scientifically stated, a volume of salt water is heavier than an equal volume of tap water because salt water has a higher density than tap water. Tap water is relatively pure, typically containing small amounts of mineral salts and smaller amounts of organic matter.

Heavy water is water in which the usual hydrogen atoms in H2O are replaced by deuterium atoms to form D2O. Tritium atoms contain one proton and two neutrons, resulting in an unstable isotope. Basically, most heavy water is very slightly radioactive from the extra tritiated water.

Distilled water is safe to drink. But you’ll probably find it flat or bland. That’s because it’s stripped of important minerals like calcium, sodium, and magnesium that give tap water its familiar flavor.

Distilled water isn’t likely to dramatically improve your health, but it probably won’t hurt it either. If you don’t mind the taste and you get enough minerals from a well-balanced diet, it’s fine to drink distilled. You can also use distilled water around the house.

Distilled water’s little victory. Distilled water may lack the minerals and nutrients of spring and mineral water, but the distilling process can be used to remove toxic metals and chemicals from the water. While there are home distillers, it is best to go with industrially distilled water instead.
