Basic Chemistry Definition - What You Need to Know

Basic Chemistry Definition - What You Need to KnowA chemistry definition can be a fascinating read if you enjoy chemistry, have an interest in chemistry, or are a student of science. It can also be daunting to a layperson who does not know much about the subject. If you wish to understand and apply chemistry definitions, here are some basic ones that you may find useful.Chemistry is the study of the molecules and compounds that make up the universe. The most common type of chemistry you will encounter in your course of study is organic chemistry, which involves the study of the chemical reactions between two or more organic molecules and the action of physical forces between them. Many other types of chemistry exist, including materials chemistry, which involves the study of the properties of different materials.A chemical bond is a sort of link between two molecules. The atoms of the molecules must be arranged in the correct way so that their electrons are evenly distributed, so tha t they both move to the same direction, and so that they make contact with each other. The electron density of the atoms determines the physical properties of the molecules. An atom that has fewer electrons is said to be negatively charged. In the case of non-living material, these properties are mostly determined by the material itself.A compound is a series of molecules that share one or more characteristics. A compound is therefore often considered to be a composite object, since it is composed of many different elements. The fact that there are several different compounds, as well as that different elements vary in chemical composition, provides a rich source of knowledge for students.A compound is further broken down into a molar mass and a molecular mass. The molar mass of a compound is the number of molecules of a substance that needs to be added to make it one molecule. The molecular mass is the number of atoms that make up the compound.Free radicals are unstable molecules t hat can replace a highly reactive molecular species with another one. However, a free radical is a molecule that has lost one or more electrons. This makes the molecule less reactive, and the loss of a single electron will cause the molecule to become either a hydrogen ion or a neutral molecule.Molecules consist of one or more atoms and a single charge. The number of atoms of the molecule is the same as the number of electrons that the atom possesses. The atomic number, also known as the atomic weight, determines the charges of the atoms.Chemical bonding is a binding of the atoms of one compound to those of another. Two molecular units are said to be bonded if their atoms lie next to each other. The bonds between atoms are called covalent bonds, while the bonds between atoms that share electrons are called electrostatic bonds.
