4.

Which of the following will have a larger atomic radius than Zinc?

a)

Gallium

b)

Aluminum

c)

Magnesium

d)

Strontium

5.
As you move down a group, atomic radius increases because - 
a)
you add more and more neutrons
b)
you add more and more protons
c)
you add more and more shells (energy levels)
d)
you add more atomic mass
6.

Francium (Fr) has the lowest ionization energy in Group 1 because -

a)

it has the smallest number of valence electrons

b)

it has the greatest atomic mass

c)

it has the greatest number of protons, so it attracts its electrons the strongest

d)

its 1 valence electron is very far from the nucleus with a lot of shielding from the nucleus, so little energy is needed to remove it

20.
The graph above shows the ionization energy values as the elements are arranged on the periodic table. Which conclusion cannot be drawn from the graph?
a)
The ionization energy drops significantly as you move down a group because the valence electrons are in a shell further from the nucleus.
b)
The ionization energy increases gradually as you move right across a period because the valence electrons are in a shell further from the nucleus.
c)
The ionization energy increases gradually as you move right across a period because you are adding more protons.
d)
The ionization energy increases when the valence electrons are more attracted to the nucleus.
