as electrons are sequentially removed from an atom, energy is required to remove each electron
more
less
the same

Explanation:

When electrons are removed one - by - one from an atom, the remaining electrons experience a higher effective nuclear charge. This is because the number of protons in the nucleus remains the same while the number of electrons (which shield the nuclear charge) decreases. According to Coulomb's law, the force of attraction between the nucleus and the remaining electrons increases. Since ionization energy is related to overcoming this attractive force, more energy is required to remove each subsequent electron.
