FAQs on Quick Revision: Atoms - Physics Class 12 - NEET

1. What are atoms?
Ans. Atoms are the basic building blocks of matter. They are the smallest unit of an element that retains the chemical properties of that element. Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons.
2. How are atoms structured?
Ans. Atoms are structured with a nucleus at the center, which contains protons and neutrons. Electrons orbit around the nucleus in specific energy levels or shells. The number of protons in the nucleus determines the element and its atomic number.
3. What is the significance of atomic number?
Ans. The atomic number of an atom corresponds to the number of protons in its nucleus. It is a crucial property as it determines the element's identity. Elements with different atomic numbers have distinct chemical properties and behave differently in reactions.
4. Can atoms be split?
Ans. Yes, atoms can be split through a process called nuclear fission. This process involves breaking apart the nucleus of an atom, usually a heavy element like uranium or plutonium. Nuclear fission releases a tremendous amount of energy and is used in nuclear power plants and atomic bombs.
5. How do atoms form molecules?
Ans. Atoms form molecules through chemical bonding. They can either share electrons, known as covalent bonding, or transfer electrons, known as ionic bonding. These bonds between atoms create stable structures and allow them to combine in various ways, forming compounds and molecules.
