FAQs on Atomic Structure - Chemistry, General Science, Exam Preparation Video Lecture - SSC CGL Tier 2 - Study Material, Online Tests, Previous Year

1. What is the atomic structure?
Ans. The atomic structure refers to the organization and arrangement of subatomic particles within an atom. It consists of a nucleus at the center, which contains protons and neutrons, and electrons orbiting around the nucleus in specific energy levels or shells.
2. What are subatomic particles?
Ans. Subatomic particles are the building blocks of atoms. They include protons, neutrons, and electrons. Protons carry a positive charge, neutrons are neutral, and electrons carry a negative charge. Protons and neutrons are located in the nucleus, while electrons are found in the electron shells surrounding the nucleus.
3. How are protons, neutrons, and electrons arranged in an atom?
Ans. Protons and neutrons are densely packed within the atomic nucleus. Electrons are arranged in specific energy levels or shells around the nucleus. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and so on. The arrangement of electrons follows the "2-8-8" rule, where the first shell is filled before moving on to the next.
4. What is the significance of the atomic structure?
Ans. The atomic structure is significant because it determines the chemical and physical properties of an element. The number of protons in the nucleus defines an element's atomic number, which determines its identity. The arrangement of electrons determines an element's reactivity and bonding behavior. Understanding atomic structure is crucial in explaining various chemical phenomena and reactions.
5. How do scientists study the atomic structure?
Ans. Scientists study the atomic structure through various experimental techniques. These include spectroscopy, which involves analyzing the interaction of matter with electromagnetic radiation, such as light. X-ray crystallography is another method that helps determine the arrangement of atoms within a crystal. Particle accelerators and electron microscopes are also used to investigate the atomic structure by studying the behavior and interactions of subatomic particles.
