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 ...

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 ...

There are three types of bonds in chemistry: ionic, covalent, and metallic bonds. In this article, we will look at the differences between ionic and covalent bonds. Chemical bonding is the force of ...
