FAQs on Mind Map: Nuclei - Physics Class 12 - NEET

1. What are nuclei?
Ans. Nuclei are the central part of an atom that contains protons and neutrons. They are responsible for determining the chemical and physical properties of an element.
2. How do nuclei contribute to the stability of an atom?
Ans. The stability of an atom is determined by the balance between the number of protons and neutrons in its nucleus. If the number of protons and neutrons is not in balance, the atom may become unstable and undergo radioactive decay.
3. Can nuclei of different elements have the same number of neutrons?
Ans. Yes, nuclei of different elements can have the same number of neutrons. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons.
4. What is nuclear fusion and how does it occur in the Sun?
Ans. Nuclear fusion is a process in which two atomic nuclei combine to form a heavier nucleus. In the Sun, nuclear fusion occurs when hydrogen nuclei (protons) combine to form helium nuclei. This process releases a large amount of energy in the form of light and heat.
5. How are the properties of an element determined by its nucleus?
Ans. The properties of an element are determined by the number of protons in its nucleus, also known as its atomic number. The number of protons determines the element's chemical properties, while the number of neutrons determines its isotopic form and can affect its stability.
