On the basis of periodic trends, determine the element with the higher first ion

Question

On the basis of periodic trends, determine the element with the higher first ionization energy in each pair (if possible). Match the elements in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. Of C or P, the element with the higher first ionization energy is C. Of Ca or Sr, the element with the higher first ionization energy is Ca. Of Sn or I, the element with the higher first ionization energy is I. Of F or S, the element with the higher first ionization energy is F.

Explanation / Answer

1.

of C or P, Phosphorous is having high ionisation energy than Carbon because, phosphorous has half filled configuration, so it is stable

2.

Ca is having high ionisation energy because in groups ionisation energy decreases.

3.

Iodine is having high ionisation potential than Sn because in periods the ionisation energy increases.

4.

Flourine is having high ionisation potential than S because Flourine has small size than Sulphur
