Answer 1

Answer:

Second ionisation energy is the energy required to remove outermost shell electron after removing one first

By name we can also guess it's meaning it says ionisation energy and ion means atom with charge hence if we remove one or more than one electron from atom it will get ionised and energy required to remove that one electron is called ionisation energy

we name the successive ionisation energies as first ionisation energy and second ionisation energy

Na+I.E→ Na+
