Welcome to Part 6 of our "Atoms and Molecules" series for Class 9 Chemistry! In this crucial episode, we delve into the Mole Concept, focusing specifically on the Deleted Portion from the syllabus. Whether you're preparing for exams or seeking a clearer understanding of this fundamental topic, this video is designed to help you navigate the key concepts and stay ahead of the curve.

An atom is the smallest unit of matter. It possesses the characteristics of an element. A nucleus is a compact centre surrounded by a succession of surrounding shells that make up an atom. These shells have electrons in them. Protons and neutrons are found in the nucleus. Neutrons have a neutral charge, while protons have a positive charge. Access our Structure of Atom Notes to get better understanding of this concept.

A molecule is made up of two or more atoms that are securely bonded together. Diatomic molecules are those that are made up of two atoms. Diatomic molecules include oxygen, nitrogen, hydrogen, and iodine. The diatomic molecules make up the majority of the Earth’s atmosphere. The smallest component of a substance is a molecule.

The mole concept is a method of counting particles. It is based on the number of atoms in 12 grams of carbon-12. This number is called a mole. A mole is equal to 6.022 x 1023 particles.
