It's water, steam, or ice. It's two parts hydrogen and 1 part oxygen.
In science, H2O stands for water.
To understand this acronym, it's useful to know that in the field of chemistry, chemical compounds are often represented using symbols and formulas. H2O is a chemical formula that represents a molecule of water.
Now, let's break down the acronym itself:
- The "H" represents the element hydrogen. In the periodic table, hydrogen is assigned the symbol H.
- The "2" subscript indicates that there are two atoms of hydrogen in the molecule.
- The "O" represents the element oxygen. In the periodic table, oxygen is assigned the symbol O.
So, when you see the term H2O in science, it refers to the compound water, composed of two hydrogen atoms bonded to one oxygen atom.
