Question

q.13. which statement correctly describes the relationship between atomic size and ionization energy?
a) larger atoms have higher ionization energies
b) smaller atoms have lower ionization energies
c) larger atoms have lower ionization energies
ans.

Explanation:

Ionization energy is the energy required to remove an electron from an atom. Larger atoms have electrons that are farther from the nucleus and less strongly attracted. So, it is easier (requires less energy) to remove an electron from a larger atom compared to a smaller atom (where electrons are closer to the nucleus and more strongly held).

Answer:

C. Larger atoms have lower ionization energies
