Question

=The minimum amount of energy required to remove an electron from on unipositive cation is called------
a.2nd ionisation energy.
b.1st ionisation energy.
c.3rd ionisation energy.
d.none of these above.​

Answer 1

The energy required to remove an electron from an element is defined as first IP. Since the ion is unipositive which means it has already lost one electron so the energy needed to remove one more electron will be abbreviated as second IP.
