Class 10 Chemistry Carbon and Its Compounds Covalent bond in carbon The elements having less than 8 electrons in their outermost shell always have a tendency to attain an octet in order to attain a noble gas configuration by gaining or losing electron forming ionic compounds. 4. Lesson 5 recaps the various models of bonding. Chemical bonding is basically defined as the attracting force between atoms, molecules or ions that enables the formation of chemical compounds. 5. (a) When the nuclei of two reacting atoms are of unequal mass, then a bond so formed is called a polar covalent bond. Thus, chapter 2 in Selina textbook deals with this concept in detail and it also covers all the underlying topics like the types of bonds, structure and characteristic properties of bonds and its compounds. (b) The atoms of covalent compounds are bound tightly to each other in stable molecules, but, (c) Electrovalent compounds dissolve in polar solvents like water because the forces of, (d) Since it takes a lot of energy to break the positive and negative charges apart from each. 10. There are three types of Chemical Bonds : 1) Electrovalent(ionic) Bond is formed as a result of the transfer of electrons from one atom of an element to one atom of another element. iii.
