Formula units are the simplest whole-number ratio of atoms in a compound. They are often used in chemistry to represent the composition of an ionic compound, such as salts. Calculating formula units ...

A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. The ratio of each element is ...

Cations can be identified with flame tests or precipitate tests using sodium hydroxide and ammonia solutions. Anions (halide, sulfate, and carbonate ions) can be identified using precipitate tests or ...

Chemical bonding is the force of attraction that holds atoms together to form molecules or compounds. There are two primary types of chemical bonds: ionic and covalent bonds. Both these bonds play a ...
