Question

In general, as you move across a period (from left to right) how does the ionization energy change?Stays the sameIncreasesDecreasesNo change

Answer 1

Increases.

Step-by-step explanation:

Remember that the ionization energy is the energy required to remove the highest energy electron from a neutral atom.

In the periodic table, this ionization energy increases across a period (from left to right), and decreases down for the groups.

Based on this logic, the answer would be increases.
