Shorthand way to show the number of atoms (or ions) in the basic structural unit of a compound. Examples are H2O, NaCl, and C6H12O6.
The ratio of elements in a substance. For example: the chemical formula of common salt is NaCl, sodium and chlorine in a ratio of 1:1.
a combination of symbols that represent elements in a substance with subscripts showing the number of atoms of each element; a shorthand method used to show the number and type of atoms present in the smallest representative unit of a substance; the chemical formula of ammonia, with one nitrogen and three hydrogens, is NH3.
a representation of a substance using symbols for its constituent elements
a combination of chemical symbols that represents the chemical composition of a compound
a combination of elemental symbols and subscript numbers that is used to show the composition of a compound
a recipe for the compound
a shorthand way of using symbols
a statement in chemical symbols of the composition of one formula unit of a compound
a type of "shorthand" used to describe a molecule
the chemical symbols that represent a compound; for example, H20 represents water
a representation of a molecule in which the symbols for the elements are used to indicate the types of atoms present and subscripts are used to show the relative numbers of atoms.
The scientific method of describing what elements a material is composed of.
a notation for a chemical compound using elemental symbols and subscripts to show how many atoms of each element are present
sometimes called the molecular formula, indicates the elements that make up a chemical.
A chemical formula (also called molecular formula) is a concise way of expressing information about the atoms that constitute a particular chemical compound. A chemical formula is also a short way of showing how a chemical reaction occurs. For molecular compounds, it identifies each constituent element by its chemical symbol and indicates the number of atoms of each element found in each discrete molecule of that compound.
