Deuterium is found in the oceans and is abundant in saltwater. Scientist believe that all deuterium found in the world was made when the big bang occurred.

Energy is produced in the sun when two?
..particles (nuclei) fuse together to form heavier nuclei. Initially, two protons fuse together (hydrogen atom nuclei) to form deuterium. These in turn may fuse with further protons, or with another deuterium nuclei to for a helium nuclei. As the heavier nuclei form, lots of energy is released.
What produces the light and heat that comes from the sun?
Two atoms of deuterium, which is an isotope of hydrogen, fuse together. Since the mass of the resulting helium nucleus is less than the mass of the deuterium isotopes, the difference (known as the "mass defect") is liberated in the form of energy. Light, heat, and so forth. This is what you see and feel when the sun shines upon you--electromagnetic radiation released from the surface of the sun. This reaction also liberates neutrinos, most of which shine through space as though nothing were there, and through the earth as though it were clear as glass. Only a tiny, tiny fraction of solar neutrinos are stopped by the earth.
What are the four most common elements found in your solar system?
The two most common are hydrogen (90%), helium (9%) and the rest make up the final 1% The oceans are 1/3 hydrogen, we have relatively little hydrogen on the inner planets because the sun's radiation "blew" most of it (the lightest element) to the outer planets like Jupiter, which is made mostly of hydrogen and is more massive than all of the other planets combined.
How does fusion in the sun happen?
At sun's surface, the temperature is enough for two hydrogen(deuterium) molecules to fuse and form a helium molecule. Due to availability of optimum temperature at the surface of sun, the reaction takes place continuously and energy due to nuclear fusion is continuously liberated.
Why is there a lower mass limit of 0.08 solar-masses for main-sequence stars?
Below about 0.08 solar masses an object will not be able to ignite nuclear fusion. There may be small amounts of deuterium fusion, but it is not sustainable. Objects between 0.08 solar masses and about 13 Jupiter masses are called brown dwarfs.
What elements are in deuterium?
Deuterium is an isotope of hydrogen.
Is deuterium radioactive?
No, deuterium is stable. It is Tritium that is radioactive.
Isotope of hydrogen with one neutron?
deuterium
Who discovered deuterium and when?
Deuterium was discovered by Harold Urey in 1931.
Who discovered deuterium?
Deuterium was discovered in 1931 by Harold Urey.
Is deuterium fluoride an acid or a base?
Deuterium flouride is an acid
Why and how Deuterium is responsible for softening of water?
Water is not softened with deuterium.
Why do you see so little deuterium today?
When the Earth first formed, there was an abundant amount of deuterium in the atmosphere. Today, most of the deuterium has fused into helium and because of that, there is little deuterium left.
What is a deuterium example of?
Deuterium is an example of natural, non-radioactive isotope; deuterium is the isotope of hydrogen with 1 proton and 1 neutron.
What is the symbol for the deuterium isotope of hydrogen?
Hydrogen-2 is commonly referred to as deuterium, in addition to that it is known as Deuterium-1
What form of hydrogen has 1 proton and one neutron in its nucleus?
Regular hydrogen.
What are the main differences of deuterium and hydrogen?
Deuterium is hydrogen. The difference between deuterium and protium (the regular hydrogen) is that deuterium has an extra neutron. As a result, there are some differences in physical properties such as density, boiling point, etc.
