The Greeks proposed the existence of five basic elements. Of these, four were the physical elements—fire, air, water, and earth—of which the entire world is composed. Alchemists eventually associated four triangular symbols to represent these elements.
Water is, in fact, a chemical. Its chemical formula is H2O (or, less commonly, HOH), which is what this website is named after. H2O is also one of the most wellknown chemical formulas. When properly written, the "2" after the H is written in subscript (as you can see in the banner above), but due to formatting restrictions it will simply be
Zinc is a chemical element. It''s not composed of other elements, so it has no "formula". The symbol for zinc is '' Zn ''.

A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H 2 O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It''s also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other.
Ice is the solid form of water that is created when water freezes at a temperature of zero degrees Celsius, so it has the same chemical formula of water, which is H2O. Water consists of two atoms of hydrogen and one atom of oxygen.
May 08, 2019· Water which is most important component of life freely available and forms 70 percent of human body is formed by interaction between two freely available elements available in environment that is Hydrogen and Oxygen. As single molecule of Hydrogen...
The chemical formula for water vapor is H 2 O. Water is a unique compound because it has the ability to exist on the earth''s surface in all three forms: liquid, solid (ice), and gas (water vapor). Water vapor is the gas phase of water, and is invisible. The measure of the amount of water vapor suspended in the air is what is known as humidity.
There are three isotopes of hydrogen. The usual chemical formula for water assumes the hydrogen atoms consist of the isotope protium (one proton, no neutrons). Heavy water is also possible, in which one or more of the atoms of hydrogen consist of deuterium (symbol D) or tritium (symbol T). Other forms of the chemical formula for water include D 2 O, DHO, T 2 O, and THO.
Water, H 2 O. Water is a simple compound with a set of unique properties that are essential for life. The chemical formula for water is H 2 O and its proper chemical name is dihydrogen monoxide. Water contains two parts hydrogen to one part oxygen.
