For elements in Group 16, how does the electronegativity change as you go down the group?

• decreases

• increases

• remains the same

• none of the above

Which atom has the largest atomic radius?

• potassium
• rubidium 
• francium
• cesium

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 nuetrons

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

• the atoms have more mass, which increases the gravitational pull

• it doesn't, atoms get bigger going from left to right because of the additional protons and electrons that are being added.

• effective nuclear charge tends to increase

• atoms lose energy levels make them smaller
