What do you know about a chemical compound by looking at its chemical formula?

Answer 1

the number and kinds of atoms in the compound
In an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.

Answer 2

Every element has a symbol which consists of either one letter such as O for oxygen, H for hydrogen etc., or two letters, such as Fe for iron, Mg for magnesium, Cl for chlorine, etc. When you see that kind of symbol, which is found in the Periodic Table of elements, you will know that it is an element and not a compound. If you see two or more of these symbols of elements together, such as H2O which is water, or MgCl2, magnesium chloride, you will know that this is a compound.

Answer 3

If the formula for the substance has only one chemical element in it (for example, Fe, Cu, O₂, etc.), then it is an element. If it has more than one chemical element in it (for example, H₂O, NH₃, etc.), then it is a compound.

Answer 4

The chemical formula of a compound provides information about the types of elements present in the compound and their relative ratios. It does not provide information about the structure, properties, or behavior of the compound. Additional analysis, such as spectroscopy or experimental data, is needed to fully understand a compound.

Answer 5

the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.

Answer 6

The identity of all the chemical elements present in the compound and the number of atoms of each kind in one molecule of the compound.

Answer 7

The chemical formula is representative for the chemical composition of a compound.
