What will happen? If – i. inert elements lose one of the outermost electrons. ii. atomic size of metals decreases. iii. maximum capacity of outermost shell of an atom becomes seven. |

Answer» i. If inert elements lose one of the outermost electrons, they will no longer be inert. They will acquire an electron to become stable again. ii. If the atomic size of metals decreases, the electrostatic force of attraction between the nucleus and the outermost electrons will increase as the distance between them decreases. Thus, it will be difficult for the metal atom to lose its outermost electron. Hence, their metallic character will decrease. iii. If the maximum capacity of outermost shell of an atom becomes seven, then the eighth electron in the outermost shell of an inert gas (excluding He) will shift to the next shell. Thus, the inert gases will no longer be inert and new set of elements (halogens) will have stable electronic configuration. |
