Question

what is the trend in ionization energy as you move across period 2, from li to ne? decreases stays the same increases

Explanation:

As you move across a period from left to right (from Li to Ne in period 2), the nuclear charge increases while the shielding effect remains relatively constant. This leads to a stronger attraction between the nucleus and the out - most electrons, making it harder to remove an electron. So, ionization energy increases.

Answer:

C. Increases
