Answer questionon the basis of your understanding of the followingparagraph and related studied concepts.Sodium atom has one electron in the outermost shell. If it loses the electron from its M-shell, then it L-shell now becomes the outermost shell and that has a stable octet. The nucleus of this atom still has 11 protons but the number of electrons has become 10, so there is a net positive charge giving us a sodium cation Na^+ . On the other hand, chlorine provides us a negative ion, Cl^-by gaining the electron from Na atom. In this way the octet of Cl is also completed. These two atoms have a give and-take relationship. Thus Na^+and Cl^- being oppositely charged in nature form a bond between them called ionic bond. The compounds obtained in this manner are called ionic compounds. Give two properties of ionic compounds. |
| Answer» SOLUTION :(i) Ionic COMPOUNDS have HIGH MELTING and BOILING points. (ii) Ionic compounds are soluble in water and insoluble in organic solvents. | |
