The Alkali metals (namely, Lithium, sodium, Potassium, Rubidium, Caesium and Francium in that order).
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).
Each element can form stable, less stable or unstable compounds.
Two elements, namely hydrogen and oxygen
unstable, think about it.
Unstable chemical elements are disintegrated by radioactive decay.

Unstable chemical elements are disintegrated by radioactive decay.
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.
The water molecule contains two different elements chemically combined, which makes it a compound. A compound is a pure substance that contains two or more different elements chemically combined.
Hydrogen and Oxygen
Dalton discovered this in 1803.
Hydroden and oxygen. H2o
All elements have unstable isotopes so the answer would be everywhere. However if you mean 'elements with only unstable isotopes' thennumber 43 Technetiumnumber 61 Promethiumeverything above 92
Water is H2O, two hydrogen atoms and one oxygen atoms.
