NEET Chemistry Ionization Energy MCQ Question
Which combination of statements about ionization energy is correct?
Ionization energy is always positive; it is easier to remove an electron from a neutral atom than from a positively charged ion.
The first ionization enthalpy for an element is the energy required to remove the second most loosely bound electron.
Ionization enthalpy increases as you move down a group due to increased atomic size.
The second ionization enthalpy is always higher than the first due to the increased positive charge of the ion.
Correct Answer
Detailed Explanation
Ionization energy is always positive as energy is required to remove electrons. The second ionization enthalpy is higher than the first because it is more difficult to remove an electron from a positively charged ion compared to a neutral atom, as stated in the NCERT context.
