H2o
H20.
Strictly, only elements have chemical "symbols". Compounds such as water have chemical formulas, and the one for water is H2O.
Chemical symbols for compounds are written by combining the chemical symbols of the elements in the compound, along with subscripts to indicate the number of atoms of each element present. For example, water (H2O) is composed of two hydrogen atoms and one oxygen atom. The chemical symbols are always listed with the element that appears first in the compound listed first.
Chemical symbols indicate elements.
Any chemical compound is composed of at least two elements. Each element has its own chemical symbol. So, it is logic that any chemical compound should have at least two chemical symbols in its formula. As an example, water is composed of hydrogen (H) and oxygen (O) and water chemical formula is (H 2 O).
State symbols in a chemical equation indicate the physical state of the reactants and products. Common state symbols include (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water).
Chemical symbols can consist of one or two symbols. The chemical symbol for oxygen is O.
Symbols of chemical elements are derived from the chemical name.
All of the symbols used in chemical equations are up on the Periodic Table.
