Question

The ionisation energy is lowest for. (A)Nitrogen (B)Oxygen (C)Fluorine (D)Neon​

Answer 1

nitrogen has lowest ionization energy

Answer 2

The ionisation energy is lowest for (D) Neon.

Explanation for the answer:

• Nitrogen has 5 electrons in their outermost orbit.
• Oxygen has 6 electrons in their outermost orbit.
• Fluorine has 7 electrons in their outermost orbit.
• Neon does not want to lose one of its electrons to disrupt its stability. So, it has the highest ionization energy.
• Thus, a very very large amount of energy will be required to remove one of its electrons.
• Hence, the correct answer among all the options is option (D) Neon.
