What in the world is IONIZATION ENERGY?!?

The video tutorial explains ionization energy, the energy required to remove an electron from an atom. It discusses the trends of ionization energy on the periodic table, noting that it increases as you move up a group and from left to right across a period. The video uses examples to illustrate these trends, emphasizing the role of energy levels and the number of protons in determining ionization energy. It also highlights that these trends are not absolute laws and have exceptions.

What is ionization energy?

• The energy required to add an electron to an atom

• The energy required to form a chemical bond

• The energy required to remove an electron from an atom

• The energy required to split an atom

Which of the following best describes the trend of ionization energy across the periodic table?

• It remains constant across the table

• It increases as you move up and to the right

• It increases as you move down and to the left

• It decreases as you move up and to the right

Why does ionization energy increase as you move from the bottom to the top of the periodic table?

• Atoms have fewer energy levels at the top

• Atoms have more energy levels at the top

• Atoms have more protons at the top

• Atoms have fewer protons at the top

Which element would have a higher ionization energy, lithium or hydrogen, and why?

• Hydrogen, because it has fewer energy levels

• Lithium, because it has more energy levels

• Hydrogen, because it has more protons

• Lithium, because it has fewer protons

As you move from left to right across the periodic table, what happens to the number of protons?

• It increases

• It decreases

• It remains the same

• It fluctuates

Why does oxygen have a higher ionization energy than lithium?

• Oxygen is in a lower period

• Oxygen has more energy levels

• Oxygen has fewer protons

• Oxygen has more protons

When comparing elements with the same number of energy levels, what factor determines ionization energy?

• The number of protons

• The number of electrons

• The number of neutrons

• The atomic mass
