Ionization Energy and Periodic Trends Quiz

What is ionization energy primarily concerned with?

• Increasing the atomic mass

• Adding electrons to an atom

• Removing the outermost electron from an atom

• Changing the atomic number

Which atom has a stronger grip on its outer electron, lithium or sodium, and why?

• Lithium, because it has more protons

• Sodium, because it is heavier

• Lithium, because it has a smaller atomic radius

• Sodium, because it has more energy levels

What effect does atomic size have on the ease of removing an electron?

• Smaller atoms hold electrons more loosely

• Larger atoms hold electrons more tightly

• Larger atoms have weaker electron attraction

• Atomic size has no effect on electron removal
