B) change from metals to nonmetals.

Step-by-step explanation:

For example, alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons (one electron, earth alkaline metals (right next to alkaline metals) have higher ionization energy than alkaline metals, because they have two valence electrons.

Nonmetals are far right in the main group and they have highest ionization energy, because they have many valence electrons.

Atomic number is the number of protons, which is characteristic of a chemical element. Atomic number increases from left to right in Periodic table.
