Chemical Bonding and Molecular Structure — Basic Introduction  Class 11 CBSE Chemistry: Chemical Bonding and Molecular Structure – Complete Question Bank 1. Matter is made up of one or different types of elements. Easy meaning: All matter around us is made up of elements . An element contains only one type of atom . Examples: Hydrogen (H), Oxygen (O), Sodium (Na), Chlorine (Cl). NEET point: 👉 Matter → Elements → Atoms 2. Under normal conditions, no other element exists as an independent atom in nature, except noble gases. Easy meaning: Most elements do not remain as single, separate atoms in nature. They usually combine with other atoms to become more stable. Noble gases are an important exception. Examples of noble gases: He, Ne, Ar, Kr, Xe, Rn Why are noble gases stable? Their outermost shell is completely filled. Therefore, they generally do not need to form chemical bonds. NEET point: 👉 Noble gases generally exist as monoatomic gases . 3. A group of atoms is found to exist ...
