In chemistry, a molecule is the smallest particle of an element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms, which are the basic units of matter. The term molecule comes from the Latin word molecula, meaning “little mass.” In other sciences, such as physics, a molecule is a collection of atoms held together by forces that can be either electrical or gravitational. The size of a molecule can range from two atoms to trillions of atoms. The study of molecules is called molecular science or molecular biology.
The word “molecule” comes from the Latin word “moles”, meaning “mass” or “unit”.
The term “molecule” is a root word derived from the Latin moles, which translates roughly to mean mass or unit. Unique to molecular science and chemistry, it defines the smallest physical particle found in any chemical element or compound. It is composed of atoms held together by covalent bonds and other intermolecular forces. In its most basic form, a molecule consists of two or more atoms linked together through strong chemical bonds. Even when broken apart, molecules can reform themselves under the right conditions. From this definition alone, we can see that molecules possess unique properties that play an incredibly important role in how matter behaves and interacts with itself.

At the atomic level, a molecule is the smallest division of an element or compound. It consists of two or more atoms that are held together by bonds and retain the same chemical properties as its larger form. Molecules come in various shapes and sizes and some energy is required to break them apart. This makes them incredibly stable, which allows them to join up with others of their kind to create all kinds of substances, from water droplets, to amino acids in living cells, to the plastics that comprise our consumer goods. The versatility of molecules and their ability to undergo complex transformations make them an interesting area for scientific study.
Molecules are made up of atoms, which are the smallest particles of an element that have the chemical properties of that element.
Molecules are everywhere and understanding how they’re composed gives us a better grasp of chemistry. All molecules are made up of atoms, the fundamental building blocks of matter. Atoms are the smallest particles that hold the chemical properties of an element and come together to form compounds. When multiple atoms combine to form a molecule, they create a new property that would be difficult to observe in single atoms. This is essential for understanding the complexity of our environment on a molecular level.
Atoms are held together by forces called bonds, which can be either ionic (electrostatic) or covalent (sharing electrons).
Atoms form bonds through the sharing or transfer of electrons. Ionic bonds occur when an electron is transferred from one atom to another, which creates an electrical imbalance between them and they are attracted to each other to restore balance. Covalent bonds form when atoms share electrons in order to create a full outer shell. Each atom involved in a covalent bond benefits from increased stability as it achieves a complete set of valence electrons. The formation of these bonds can vary significantly depending on certain factors including size, charge, and energy levels, making them one of the most important components governing the behavior of molecules and compounds.
Ionic bonds occur when one atom donates an electron to another atom, forming a charged particle called an ion.
Ionic bonds are a type of chemical bond that is formed when one atom donates an electron to another. This creates oppositely charged ions, with the atom which gave away the electron becoming positively charged, and the atom which accepted it bearing a negative charge. The attraction between these charged particles is what keeps them bonded together. Ionic bonds can form between two different elements, or even more than two if multiple atoms exchange electrons simultaneously. These types of bonds are some of the strongest in nature, and are responsible for holding together the molecules that make up many different compounds and substances such as sea salt or table salt.
Covalent bonds occur when two atoms share electrons equally between them.
Covalent bonds are a type of chemical bond formed by the sharing of two electrons between two atoms. These bonds form when the atoms involved have similar electronegativities, creating an equal sharing of electrons among them. As a result, the atoms can become more stabilized and acquire more energy than they would individually. Although their strength varies depending on the types of atoms involved, covalent bonds can be quite strong and often difficult to break. They play a significant role in organic chemistry, providing molecules with increased stability and structure.
