Correct Answer
Option B
Explanation
The correct order of first ionization enthalpy among the elements given is indeed represented by Option 2: $Al<Mg<Si<S<P$. Let's delve into the reasoning behind this order and why the other options are incorrect. ### Explanation for Option 2: $Al<Mg<Si<S<P$ 1. Ionization Enthalpy Trend Across a Period: - As we move across a period from left to right in the periodic table, the ionization enthalpy generally increases. This is because the…Read More
