Arrange the following elements according to the trend of ionization energies. (C, N, Ne, B)
Correct answer: C. B < C < N < Ne
- A. Ne < N < C < B
- B. B < N < C < Ne
- C. B < C < N < Ne
- D. Ne < B < C < N
Explanation
As they move along the period towards the right the ionization energy increases. It is a fact and should be memorised.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
