SSC MCQ Question Ans. Chemical Bonds
SSC MCQ Question Ans. Chemical Bonds. Inert gases are stable in nature as mono-atomic gases, except these gases the atoms of other elements cannot exist independently in nature. Molecules of fundamental gases are di-atomic like O2, N2, F2, Cl2, Br2 etc. Again molecules of some elements consist of more than two atoms. For example O3, P4, S8. Again, compounds are formed by the combination of atoms of different elements like NaCl, H2O, HCl, CH4 etc. In all molecules atoms remain attached together by a special kind of attraction force; this force is called the binding force.
Generally, at the bond formation, every atom wants to achieve the electronic configuration of its nearest inert gas at its last energy level. Generally metal and nonmetal form ionic bonds while nonmetal and nonmetal form a covalent bond. In metallic pieces metal atoms attached with one another by the metallic bond. The elements or compounds formed by three types of bonds have unique characteristics of.
