Question

Which element has highest ionisation energy P ,Na,Cl

Answer 1

Answer:

Na has highest ip

Explanation:

Na has more I.E because as we move across a period (Left to right) in periodic table I.E increases and when we move down the group (top to bottom) ionization energy decreases.

Answer 2

Answer:

Heyaa♡♡

Among these elements Chlorine (Cl) has the highest ionization energy because 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.
