Identify the wrong and correct statements accordingly:
i) As the size of the atom increases, ionisation energy decreases.
ii) As we move left to right in a period, ionisation energy decreases.
iii) As the ionisation enregy increases, metallic energy increases
iv) As the nuclear charge increases, ionisation energy increases along the period.

Explanation

ii) As we move from left to right in a period ionisation energy increases.
iii) As the ionisation energy increases, metallic character decreases.
