Atoms and Molecules

Atoms and molecules are fundamental units of matter. Let's explore these concepts in more detail:

Atoms: - Atoms are the basic building blocks of matter. - They are the smallest units of an element that retain the chemical properties of that element. - Atoms consist of a nucleus, which contains protons and neutrons, and electrons that orbit the nucleus. - The number of protons in an atom determines its atomic number and defines the element. - Different elements have different numbers of protons, neutrons, and electrons.

Molecules: - Molecules are formed when two or more atoms chemically combine. - They can be made up of atoms of the same element or different elements. - Molecules can exist as discrete units or as part of a larger structure. - The atoms in a molecule are held together by chemical bonds, which can be covalent, ionic, or metallic.

Examples: - Water (H2O) is a molecule composed of two hydrogen atoms and one oxygen atom. - Carbon dioxide (CO2) is a molecule composed of one carbon atom and two oxygen atoms.

Importance: - Atoms and molecules are essential for understanding the properties and behavior of matter. - They form the basis of chemistry, which studies the composition, structure, properties, and changes of matter.
