The concept is split into four separate elements (fire, water, air and earth), with each one consisting of six songs and lasting under half-an-hour in length. [18] The closing tracks of each volume are sonnets, [ 36 ] laid out in traditional English form ; [ 38 ] Kensrue often struggled with writing lyrics since it revolved around how the words ...
If two elements can form three compounds between them, then the third compound is a "quaternary" compound containing one atom of the first element and three of the second. [20] Dalton thought that water was a "binary compound", i.e. one hydrogen atom and one oxygen atom.
For example, carbon has three naturally occurring isotopes: all of its atoms have six protons and most have six neutrons as well, but about one per cent have seven neutrons, and a very small fraction have eight neutrons. Isotopes are never separated in the periodic table; they are always grouped together under a single element.

English chemist Humphry Davy was a pioneer in the field of electrolysis, using Alessandro Volta's voltaic pile to split up common compounds and thus isolate a series of new elements. He went on to electrolyse molten salts and discovered several new metals, especially sodium and potassium , highly reactive elements known as the alkali metals .
Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.
In thermolysis, water molecules split into hydrogen and oxygen. For example, at 2,200 °C (2,470 K; 3,990 °F) about three percent of all H 2 O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H 2, O, O 2, and OH. Other reaction products like H 2 O 2 or HO 2 remain minor. At the very high temperature of 3,000 ...
The following tables list molecules that have been detected in the interstellar medium or circumstellar matter, grouped by the number of component atoms. Neutral molecules and their molecular ions are listed in separate columns; if there is no entry in the molecule column, only the ionized form has been detected. Designations (names of ...
