Everything You'll Have Covered

What is ionization energy? How does it affect metals and nonmetals?

~ Ionization energy is the energy necessary to remove an electron from a neutral atom. It becomes easier for an atom to lose an electron as the electrons get farther away from the nucleus. The ionization energy decreases as it becomes easier for an atom to lose an electron. Metals tend to lose electrons from their compounds and nonmetals tend to gain electrons.

What happens to the ionization energy of elements as we move down the Periodic Table?

~ As we move down the Periodic Table, ionization energy decreases. As ionization energy decreases, these elements lose an electron more easily, so their metallic properties increase while their nonmetallic properties decrease.

What happens to the ionization energy of elements as we move across the Periodic Table from left to right?

~ As we move across the Periodic Table from left to right, the atomic number increases. Consequently, the charge of the nucleus and the ionization energy also increases, causing it to become more difficult for an atom to lose its electrons. In addition, an element's nonmetallic properties increase and its metallic properties decrease.
