FAQs on Chemical Bonding - 1 Video Lecture - Crash Course for IIT JAM Chemistry

1. What is chemical bonding?
Ans. Chemical bonding refers to the process by which atoms combine to form molecules or compounds. It involves the redistribution of electrons between atoms to achieve a stable electron configuration.
2. What are the different types of chemical bonds?
Ans. There are three main types of chemical bonds: ionic bonds, covalent bonds, and metallic bonds. Ionic bonds involve the transfer of electrons between atoms, covalent bonds involve the sharing of electrons, and metallic bonds involve a sea of delocalized electrons surrounding positively charged metal ions.
3. How does an ionic bond form?
Ans. An ionic bond forms when one atom transfers electrons to another atom. This occurs between a metal and a nonmetal. The metal atom loses one or more electrons to become a positively charged ion (cation), while the nonmetal atom gains those electrons to become a negatively charged ion (anion). The opposite charges attract and hold the ions together in a crystal lattice.
4. What is a covalent bond?
Ans. A covalent bond is a type of chemical bond formed by the sharing of electrons between two nonmetal atoms. In this bond, each atom contributes one or more electrons to the shared pair, resulting in a stable electron configuration for both atoms. Covalent bonds can be either polar or nonpolar, depending on the electronegativity difference between the atoms.
5. How does metallic bonding occur?
Ans. Metallic bonding occurs between metal atoms. In this type of bond, the valence electrons of metal atoms are delocalized and form a "sea" of electrons that are free to move throughout the metal. The positive metal ions are surrounded by this electron sea, creating a strong bond. This type of bonding is responsible for the unique properties of metals, such as high electrical and thermal conductivity, malleability, and ductility.
