Question

As you move across a period in the periodic table from left to right, the atomic radius decreases due to the increase in nuclear charge which pulls electrons closer. The electron affinity becomes increasingly negative as atoms are more eager to gain electrons to achieve a stable octet configuration. The first ionization energy increases because atoms are more tightly holding onto their electrons, making it harder to remove an electron.
