Table given below show a part of the Periodic TableUsing this table explain why :(i) Li and Na are considered as active metals.(ii) Atomic size of Mg is less than that of Na(iii) Fluorine is more reactive than chlorine. |

Answer» (i) They can lose electrons easier due to a bigger size, the energy required to remove an electron is less. (ii) It is because of greater effective nuclear charge in Mg. (iii) Fluorine has very small size and just needs one electron to get itself into a stable configuration to that of noble gases. Hence, they react spontaneously with elements to achieve that stable state, contributing to its high reactivity. |
