A group of two or more atoms held together by chemical bonds is called a molecule. To understand this concept, we need to understand the basics of atoms and chemical bonds.
Atoms are the building blocks of matter. They consist of a nucleus containing protons and neutrons, surrounded by orbiting electrons. Different types of atoms have different numbers of protons, neutrons, and electrons, giving them specific properties.
Chemical bonds are formed when atoms interact with each other. There are three main types of chemical bonds: covalent bonds, ionic bonds, and metallic bonds. Covalent bonds occur when atoms share electrons. Ionic bonds form when one atom transfers electrons to another, resulting in charged particles called ions. Metallic bonds occur in metals when atoms share a "sea" of electrons.
When two or more atoms come together and are held together by chemical bonds, they form a molecule. The atoms can be the same (as in an oxygen molecule, O2), or different (as in a water molecule, H2O). Molecules can be simple, containing just two atoms, or complex, containing thousands or even millions of atoms.
To determine if a group of atoms is held together by chemical bonds and thus considered a molecule, you need to analyze their arrangement and bonding behavior. This can be done using various techniques, including spectroscopy, molecular modeling, and crystallography, depending on the specific case.
So, in summary, a group of two or more atoms held together by chemical bonds is called a molecule. By understanding the basics of atoms and chemical bonding, it becomes easier to grasp the concept and determine whether a given group of atoms forms a molecule.
