Question

Energy required for the ionisation of 0.02gram atom of Mg is x kJ. The amount of energy required to ionise 1 atom of Mg is
1)x kJ
2) x/0.02NA J
3) x × 10 to the power 3 by 0.02 NA J
4) xNA kJ

Answer 1

Answer:-  The amount of energy required to ionise 1 atom of Mg is 1)x kJ Explanation:- Ionization energy is the energy required to remove a loosely bound electron from the outermost shell of an isolated gaseous atom to form an ion. Thus we can see from the above definition that when ionization energy is given to Me magnesium, electrons are lost leading to the Formation of magnesium cation. Hence the amount of energy required to ionise 1 atom of Mg is same as ionization energy.
