FAQs on Structure of Atom - 2 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 and neutrons are found in the nucleus at the center of the atom, while electrons orbit around the nucleus in various energy levels or shells.
2. How do protons and neutrons differ from electrons in terms of charge?
Ans. Protons carry a positive charge (+1), neutrons are neutral (0 charge), and electrons carry a negative charge (-1). This difference in charge is essential for the stability of atoms and the formation of chemical bonds.
3. What is the significance of the atomic number in an element?
Ans. The atomic number of an element is defined by the number of protons in its nucleus. It determines the identity of the element and its position on the periodic table. For example, an element with an atomic number of 6 is carbon.
4. How do isotopes of an element differ from each other?
Ans. Isotopes are variants of the same element that have the same number of protons but different numbers of neutrons. This results in different atomic masses. For example, carbon-12 and carbon-14 are both isotopes of carbon, with 6 protons but 6 and 8 neutrons, respectively.
5. What role do electrons play in chemical bonding?
Ans. Electrons, particularly those in the outermost shell (valence electrons), are crucial for chemical bonding. They can be shared between atoms (covalent bonding) or transferred from one atom to another (ionic bonding), which leads to the formation of molecules and compounds.
