Structure and Properties of Matter in Chemistry
Introduction
Matter is anything that has mass and volume. Chemistry is the study of matter and its properties, as well as the changes that matter undergoes. The structure of matter is the way that its atoms and molecules are arranged. The properties of matter are the characteristics that it exhibits, such as its physical state, density, and reactivity.
Basic Concepts
Atoms and Molecules
Matter is composed of atoms, which are the smallest indivisible units of an element that retain the chemical properties of that element. Atoms are composed of a nucleus surrounded by electrons. The nucleus contains protons and neutrons, which are much heavier than electrons. The number of protons in an atom's nucleus determines the element to which it belongs.
Atoms can combine with each other to form molecules. A molecule is a group of atoms that are held together by chemical bonds. The structure of a molecule determines its properties.
Chemical Bonding
Chemical bonding is the force that holds atoms together to form molecules. There are three main types of chemical bonds: covalent bonds, ionic bonds, and metallic bonds.
- Covalent bonds are formed when atoms share electrons.
- Ionic bonds are formed when one atom transfers electrons to another atom.
- Metallic bonds are formed when the electrons in a metal are shared among all of the atoms in the metal.
