FAQs on Atoms and Molecules Video Lecture - Physical Science for High School - Grade 9
| 1. What are atoms and molecules? |  |
Ans. Atoms are the basic building blocks of matter. They are the smallest unit of an element that retains its chemical properties. Molecules, on the other hand, are made up of two or more atoms chemically bonded together. They can be of the same element or different elements.
| 2. How are atoms and molecules different? | |
Ans. Atoms are the individual particles that make up elements, while molecules are formed when two or more atoms chemically combine. Atoms cannot be broken down further without losing their chemical properties, whereas molecules can be broken down into their constituent atoms.
| 3. What is the difference between an element and a compound? | |
Ans. An element is a pure substance that consists of only one type of atom. It cannot be further broken down into simpler substances by any chemical means. In contrast, a compound is a substance made up of two or more different elements chemically combined in a fixed ratio. Compounds can be broken down into their constituent elements through chemical reactions.
| 4. How do atoms form molecules? | |
Ans. Atoms form molecules through chemical bonding. There are two main types of chemical bonds: covalent bonds and ionic bonds. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another. These bonds hold the atoms together and form molecules.
| 5. Why are atoms and molecules important? | |
Ans. Atoms and molecules are important because they make up everything around us. They are the fundamental units of matter and play a crucial role in chemical reactions, biological processes, and the functioning of materials. Understanding atoms and molecules helps us understand the properties and behavior of substances, leading to advancements in various fields such as medicine, technology, and environmental science.
