NEET Chemistry Ionization Energy MCQ Question
Which statement about ionization enthalpy is true?
The second ionization enthalpy is always lower than the first.
Ionization enthalpies are always positive values.
Removing an electron from a neutral atom requires less energy than from a positively charged ion.
Ionization enthalpy is expressed in units of electron volts.
Correct Answer
Detailed Explanation
Ionization enthalpies are defined as the energy required to remove electrons from an atom, and energy is always required, making them positive. The second ionization enthalpy is higher than the first due to increased difficulty in removing an electron from a positively charged ion, as stated in the text.
