As you move down the periodic table atoms get bigger. This is because ____________.

• The atoms have more mass.

• The atoms have more protons

• The atoms have more energy levels

• The atoms have more neutrons

As you move across the periodic table atoms tend to get smaller because, ______________.

• the atoms have more mass.

• the atoms have more protons.

• the atoms have less mass

• the atoms have less electrons.

Which statement correctly and completely identifies a trend?

• Atomic radius decreases across a period and increases down a group.

• Ionization energy increases across a period and increases down a group.

• Electronegativity decreases across a period and decreases down a group.

• Ionic radius increases across a period and increases down a group.

The reason that Noble Gases do not react is because

• They are able to bond to fill their outer shell

• Their inner electron shell is filled

• Their outer electron shell is filled

• None of the above, Noble Gases are highly reactive
