Atoms – Class 12 | Chapter – 12 | Physics Short Notes Series PDF for NEET & JEE

Atoms: Atoms are the basic building blocks of matter. They are the smallest particles of an element that still retain the properties of that element. Atom are made up of three types of subatomic particles: protons, neutrons, and electrons.


In physics, atom are important because they are the fundamental units of matter, and understanding their behavior is crucial to understanding the physical world around us.

The study of atom and their interactions is the foundation of atomic physics, which deals with the behavior of atom in isolation or in small groups. This includes the study of the structure and properties of atom, as well as the interactions between atoms and other particles such as photons and other atoms.

In addition, the behavior of large collections of atoms is studied in the field of condensed matter physics. This includes the study of how atoms come together to form molecules, solids, liquids, and other complex systems, and how these systems interact with each other.

The principles of atomic physics and condensed matter physics are used in a wide range of applications, including the design of computer chips, the development of new materials, and the study of the properties of gases and liquids at high pressures and temperatures.
