Question

Atomic radii decrease, moving from left to right across a period. As a result, the electrons become closer to the nucleus. What effect does this movement have on the ionization energy (the amount of energy required to remove an electron from an atom)? The ionization energy stays the same. The ionization energy decreases. The ionization energy increases. Electrons have no effect on ionization energy.

Answer 1

The ionisation energy increases.

Step-by-step explanation:

This is because the force of attraction between the electrons and the positive nucleus will increase
