Molecule, smallest unit of a substance that shows all the chemical properties of that substance. A molecule is a group of atoms that are bound tightly together by strong chemical bonds called covalent bonds. Every molecule has a definite size. If a molecule is broken up into its atoms or into smaller groups of atoms by chemical processes, these pieces will not behave like the original molecule. A molecule can contain atoms of the same element or atoms of different elements. A substance made up of molecules that include two or more different chemical elements is called a molecular compound. An example of a molecular compound is water. Water is made of molecules that contain two hydrogen atoms and one oxygen atom. Many substances on Earth are made of molecules. Millions of molecules join together to make up the cells in humans or in any other plant or animal. The food we eat, the air we breathe, the clothes we wear, and the wood, paint, and carpeting that we use in homes are all made of molecules. Millions of different molecules exist in nature or can be made by chemists. The nature of each molecule depends on the atoms that it contains and how they link to each other. For example, the oxygen that animals require is made of molecules that have two oxygen atoms bound together. If one oxygen atom binds to a carbon atom, the molecule is instead the poisonous gas carbon monoxide. Scientists study molecules and their structures so they can better understand why substances behave the way they do. For example, molecular structure helps explain why water boils at a high temperature. Scientists and manufacturers also use their knowledge of molecules and molecular structures to make substances with desirable properties. Plastics, for instance, are laboratory-made substances that consist of enormous molecules containing thousands of atoms. By manipulating the molecular structure of plastics, chemists have created materials that stretch better, resist fading, or can be used in microwave ovens without melting. Similarly, pharmaceutical chemists use their knowledge of molecular structure to develop new drugs that more effectively ease pain or fight disease. The discovery of the structure of deoxyribonucleic acid (DNA), the molecule that contains the genetic blueprint for living organisms, opened the door to tremendous advances in medicine and industry. Knowledge of the structure of DNA has enabled physicians to understand and treat certain genetic diseases. Moreover, by manipulating DNA structure, scientists have been able to modify-or genetically engineer-organisms, creating, for example, bacteria that produce valuable drugs. Although much of our world is composed of molecules, not all substances are molecular. As we will discuss later, metals do not consist of molecules; nor do ionic compounds, which are crystalline substances such as common table salt. The atoms in metals and ionic compounds form different arrangements from those of molecular structures.
molecules are the small structure which are formed by the atoms. it helps in building of the large heavy structure
Water is a molecule.
the subscript 2 after the H indicates that the hydrogen molecule contains two (2) atoms of hydrogen
a coefficent in physical science means:a number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product that are involved in a reaction
Molecular biologists discovered deoxyribonucleic acid (DNA), the molecule that codes for genes. Every organism's genetic makeup is encoded within strands of this molecule, and the science of molecular biology provided an enormous boost for explaining the role of random mutations in evolution. Darwin had done an excellent job in describing the role of natural selection, but the incorporation of the discoveries of molecular biology into evolutionary biology became known as the "modern synthesis."

It is interesting to learn to Latin translation for terms used mainly in science. The Latin word for molecule is Ottavio.
The definition of the word translation in science is " the process by which a protein is synthesized from the information contained in a molecule of messenger RNA. "
The name of the "bubble" in science is the molecule, because if you use a professional microscope, molecules look like bubbles. The name of the "bubble" in science is the molecule, because if you use a professional microscope, molecules look like bubbles.
The prefix meaning of 4 in science is "tetra-." It represents the quantity of four units or groups. For example, a molecule with four carbon atoms may be referred to as a "tetraatomic" molecule.
