NEET Chemistry Ionization Energy MCQ Question
Which of the following statements about ionization energy is correct?
Ionization energy is always a positive value because energy is needed to remove electrons.
The second ionization energy is always less than the first ionization energy.
Ionization energy decreases as you move from left to right across a period.
Shielding effects make it easier to remove the outermost electron from an atom.
Correct Answer
Detailed Explanation
Ionization energy is always positive because energy is required to remove an electron from an atom. The first ionization enthalpy involves energy needed to remove an electron, as stated in the NCERT context.
