Three isotopes. All have one proton and one electron.
Protium has 0 neutron, Deuterium has 1 neutron, Tritium has 2 neutrons.
Known isoptopes include - 108 to 128 inclusive.
Isotopes of an element have different numbers of neutrons.
Hydrogen oxide (also known as water) contains two hydrogen atoms and one oxygen atom in each molecule.
Hydrogen and carbon combine to form many, many different compounds known as hydrocarbons. Please see the link.
Well with any element when two atoms are put together they are known as a molecule of that element. So one atom of hydrogen is known as one atom of hydrogen and two atoms of hydrogen is known as one molecule of hydrogen.
There are three known naturally occurring isotopes of hydrogen; hydrogen-1 with one proton and no neutrons, hydrogen-2 with one proton and one neutron, and hydrogen-3 with one proton and two neutrons.
Hydrogen chloride in aqueous solution is commonly known as hydrochloric acid.
There are a great many compounds made from hydrogen and carbon, and as a group they are known as hydrocarbons. Petroleum consists of hydrocarbons. Natural gas, also known as methane, formula CH4 is the simplest hydrocarbon.
There are three forms of Hydrogen (these are known as isotopes). These are normal hydrogen, deuterium and tritium.
The most common form of Hydrogen, forming more than 99.9% of all hydrogen atoms in the universe, (sometimes known as Hydrogen-1) has one proton in the nucleus and one electron ( with no neutrons ). There are, however, other forms (isotopes) of hydrogen that can be stable, such as Hydrogen-2 ( also known as deuterium ), which has one neutron and one proton in the nucleus as well as one electron.
I don't understand the question. Could you write it in better english?
