Atomic Radius & Bonding

As you move down the periodic table atoms get bigger (a larger atomic radius). 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 less mass
• the atoms have more protons.
• the atoms have less electrons.
