As you move across the periodic table atoms tend to get smaller because, ______________.
the atoms have more mass.
the atoms have less mass
the atoms have more protons.
the atoms have more electrons.
Ionization energy (and electronegativity) __________ from left to right within a period and __________ from top to bottom within a group.
decreases, increases
increases, increases
increases, decreases
decreases, decreases
Francium (Fr) has the lowest ionization energy in Group 1 because -
it has the smallest number of valence electrons
it has the greatest atomic mass
it has the greatest number of protons, so it attracts its electrons the strongest
its 1 valence electron is very far from the nucleus, so little energy is needed to remove it
Which element has the lowest ionization energy?
Potassium
Calcium
Gallium
Germanium

Carbon (C)
Neon (Ne)
Antimony (Sb)
Germanium (Ge)
