It tells what elements are in a compound and the number of each type of atom in each molecule/formula unit.
The chemical composition of the compound
This formula tells you that the compound has one atom of the element Barium and two atoms of the element Fluorine. It is called Barium Fluoride.
this formula tells the accurate ratio of a molecule or compound
The formula of a substance(element or compound) tells us the number of molecules in the in the substance(element or compound).
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
a chemical formula
A chemical formula tells what elements make up a compound and the exact number of atoms of each element in a unit of compound. :)
the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.
the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
It tells what elements are present in a molecule and how many atoms of each element are present.
It tells you what type of bonding whether; Ionic, Metallic, Covalent Network or Molecular Covalent. It tells you the elements that make up the compound. It also tells you the stage of matter; solid, liquid or gas. And since you known the elements you can find out really anything you want to know about it like; # of protons, # of neutrons, mass number, atomic weight, reactivity, etc.
