FAQs on Basic Fundamental Concepts of Chemistry - 1 Video Lecture - General Knowledge - SSC CHSL

1. What are the fundamental concepts of chemistry?
Ans. The fundamental concepts of chemistry include the study of atoms, elements, compounds, chemical reactions, and the periodic table. These concepts form the basis of understanding the composition, structure, properties, and behavior of matter.
2. What is an atom?
Ans. An atom is the basic unit of matter. It consists of a nucleus, which contains protons and neutrons, and electrons that orbit around the nucleus. Atoms are the building blocks of all elements and combine to form various compounds.
3. What is the periodic table?
Ans. The periodic table is a tabular arrangement of chemical elements based on their atomic number, electron configuration, and recurring chemical properties. It provides a systematic way to organize and classify elements according to their properties, such as metals, nonmetals, and metalloids.
4. What is a chemical reaction?
Ans. A chemical reaction is a process that involves the transformation of one or more substances into different substances. It occurs when chemical bonds are broken and new bonds are formed. Chemical reactions are represented by chemical equations and involve the conservation of mass and energy.
5. What is the difference between an element and a compound?
Ans. An element is a pure substance that consists of only one type of atom. It cannot be broken down into simpler substances by chemical means. In contrast, a compound is a substance composed of two or more different elements chemically bonded together. Compounds have unique properties distinct from their constituent elements.
