    when electron is removed by atom then it is known as 1st IP and after removing next election the energy required is known as 2nd IP. after removing each electron size of ions decreased due to increased in Zeff so IP will continuously increasing on removing each electron. so in your que. IP of n+ will be greater than n atom. lets take an example

    Ionisation energy is the amount of energy that is required to remove 1 e from the other most shell of isolated gaseous atom. we know that no. of electrons = no. of ptotons. so after removing 1 e the no. of e become less than protons so there is more attractive force between electrons and nucleus and hence size of ions become less than corresponding atom. not next electron can be removed by ion so it is difficult to remove due to effective nuclear charge
