Chemistry Question on trends in periodic table
Which of the following has the highest first ionization potential?
A
Boron
B
Nitrogen
C
Oxygen
D
Carbon
Answer
Nitrogen
Explanation
Solution
lonization Potential is the amount of energy that is required to remove an electronfrom the outermost orbit of a gaseous atom.
Out of Boron, Nitrogen, Oxygen, and Carbon - Nitrogenhas a completely half-filled stable configuration.
**Nitrogen Electronic Configuration= 1s 22s22p3 **
Due to this stable configuration, it is difficult to remove an electron and hence it requires more energy than others. So, nitrogen has the highest first ionization potential among other elements.
