FAQs on Atom Molecules - Chemistry, General Science, Exam Preparation Video Lecture - General Test Preparation for CUET

1. What are atoms and molecules?
Ans. Atoms are the basic building blocks of matter, consisting of a nucleus (composed of protons and neutrons) surrounded by electrons. Molecules, on the other hand, are formed when two or more atoms chemically bond together. They can be made up of the same type of atoms (e.g., oxygen gas - O2) or different types of atoms (e.g., water - H2O).
2. How are atoms and molecules related?
Ans. Atoms are the individual particles that make up molecules. Molecules are formed when atoms chemically combine with each other through chemical bonds. The arrangement and number of atoms in a molecule determine its properties and characteristics.
3. What is the difference between an atom and a molecule?
Ans. The main difference between an atom and a molecule is that an atom is a single particle, whereas a molecule is composed of two or more atoms chemically bonded together. Atoms are the fundamental units of matter, while molecules are the result of the combination of atoms.
4. How do atoms and molecules interact with each other?
Ans. Atoms and molecules interact with each other through various chemical reactions. These interactions involve the exchange, sharing, or transfer of electrons between atoms, resulting in the formation of new molecules or breaking down of existing ones. The interactions between atoms and molecules govern the behavior and properties of matter.
5. Why are atoms and molecules important in chemistry and general science?
Ans. Atoms and molecules are fundamental concepts in chemistry and general science. They provide the basis for understanding the structure, composition, and behavior of matter. By studying atoms and molecules, scientists can explain and predict the properties, reactions, and transformations of substances, enabling advancements in various scientific disciplines, including medicine, materials science, and environmental science.
