UNIT 1. STRUCTURE OF AN ATOM AND MASS SPECTRUM

The study of the structure of an atom helps us understand what matter is made of and how substances interact during chemical reactions. Every element consists of tiny particles called atoms, which are made up of protons, neutrons, and electrons. The arrangement and behavior of these particles determine the properties of each element.

To study atoms in more detail, scientists use advanced instruments such as the mass spectrometer, which measures the masses of atoms and their isotopes. The mass spectrum produced gives valuable information about the composition of elements, their isotopic abundance, and helps in calculating the relative atomic mass of elements accurately.

In summary, the structure of the atom explains the internal makeup of matter, while the mass spectrum provides experimental evidence of the existence and properties of isotopes.
