प्रश्न
Which element from the following has the highest ionization energy?
Explain your choice.
P, Na, CI
उत्तर
Cl
Metals have low ionisation energy and non-metals have high ionisation energy. Also, across the period, ionisation energy tends to increase. The elements P, Na and Cl belong to the third period. Na - Group 1, P - Group 15 and Cl - Group 17.
