FAQs on Structure of Atom - 1 Video Lecture - Crash Course for NEET
| 1. What are the main components of an atom? |  |
Ans. An atom is primarily composed of three subatomic particles: protons, neutrons, and electrons. Protons are positively charged particles found in the nucleus, neutrons are neutral particles also located in the nucleus, and electrons are negatively charged particles that orbit the nucleus in electron shells.
| 2. How do protons and neutrons differ in terms of charge and location? | |
Ans. Protons carry a positive charge and are located in the nucleus of an atom, which is the central part of the atom. Neutrons, on the other hand, have no charge (they are neutral) and are also located in the nucleus alongside protons. This difference in charge is crucial for the chemical properties of elements.
| 3. What is the significance of electron configuration in an atom? | |
Ans. Electron configuration refers to the distribution of electrons in the various energy levels or shells around the nucleus of an atom. It is significant because it determines how an atom interacts with other atoms, influencing its chemical behavior, reactivity, and the types of bonds it can form.
| 4. How do isotopes of an element differ from each other? | |
Ans. Isotopes of an element are variants that have the same number of protons but differ in the number of neutrons. This difference in neutron count results in varying atomic masses, but isotopes retain the same chemical properties. For example, Carbon-12 and Carbon-14 are isotopes of carbon with different neutron numbers.
| 5. What is the role of the nucleus in an atom? | |
Ans. The nucleus serves as the core of the atom, containing protons and neutrons. It is responsible for the atom's mass and positive charge due to the protons. The strong nuclear force binds protons and neutrons together, while the nucleus also influences the stability of the atom and its isotopes.
