FAQs on Atoms and Molecules- NCERT Solutions of Chapter 3 (Science) for Class 9
1.What is an Atom?
When you study ch 3 science class 9, you will have a clear concept about atoms. Atoms are the smallest component of any matter that can exist independently in nature. However, some atoms cannot exist freely and form molecules with the same type of atoms or form compounds with different atoms. Go through the class 9th science chapter 3 for a detailed explanation of the concepts related to atoms and molecules.
2. What is a Molecule, as per the NCERT solutions?
When atoms combine, they form a molecule. A minimum of two atoms can form a molecule. A molecule can be made of the same or different atoms. To completely understand the concept of molecules, refer to the atoms and molecules class 9 solutions.
3. Mention the topics included in Chapter 3 Atoms and Molecules of NCERT Solutions for Class 9 Science.

5. What is the chemical formula of compounds as per the NCERT solutions?
Chemical formulas are believed to be the symbolic representation of substances. The net charge of each ion in the formula is taken into account in the chemical formula. The radical's valency is determined by the charge of individual ions. The valency of individual ions affects how many of each type of ion will participate in the interaction. The valency of individual ions must be balanced in order to properly represent the chemical formula. Metal names should appear first, followed by non-metal names.
6. What is a molecule made up of as per the NCERT solutions?
A molecule is made up of two or more atoms linked together. In nature, a molecule can exist without restriction. Hydrogen, oxygen, and calcium molecules, for example, can exist freely in nature. Molecules can be made from the same atoms or from atoms that are different. When molecules are made up of the same type of atoms, they are referred to as element molecules. Elements such as sodium and potassium, for example. Molecules can also be formed from atoms with different properties. A compound is formed when various atoms join together.
7. What is atomic mass as per the NCERT solutions?
The atomic mass unit is the unit of mass for each atom. The atomic mass is an atom's property. The law of constant proportion and the law of mass conservation are both supported by the idea of atomic mass. The NCERT Solutions for Class 9 Science Chapter 3 Atoms and Molecules provides a thorough examination of atomic mass. There are a lot of properties of atoms that are discussed in Chapter 3 of Class 9 Science NCERT.
