• Francium (Fr)
• Sodium (Na)

Which of these elements has the lowest ionization energy?

Ionization energy __________ as you do across a period

• has no pattern

• stays the same

• decreases

• increases

Select what explains the ionization energy trend in a period

• more valence electrons

• their is a weak pull between electrons from the nucleus, making them easily moveable

• larger effective nuclear charge

• electrons are further from the nucleus

Ionization energy __________ as you go down a group.

Ionization energy depends on what two things?

• Number of neutrons and distance of the outermost electron
• Number of electrons and size of the atom
• Number of protons and size of the atom
• Distance between electrons and nucleus and effective nuclear charge.
