• Lower left

• Upper right

• Lower right

• Center

• Upper right

• Lower left

• Upper left

• Center

If you were asked to find the most reactive metals and the most metallic elements on the Periodic Table, what reasoning would you use to locate them?

• Both are found in the lower left because reactivity and metallic character increase in that direction.

• Both are found in the upper right because reactivity and metallic character increase in that direction.

• Most reactive metals are in the center, while most metallic elements are in the upper left.

• Most reactive metals are in the lower right, while most metallic elements are in the upper right.

Explain why the atomic radius increases as you move down a group in the periodic table.

• There are fewer protons, so electrons are less tightly held.

• More energy levels are added, increasing the size of the atom.

• Electrons are lost, making the atom larger.

• The number of neutrons increases, causing the atom to expand.

What happens to the metallic character of elements as you move across a period (from left to right) in the periodic table?

• It increases

• It stays the same

• It decreases

• It fluctuates randomly

How does the reactivity of metals change as you move across the periodic table?

• Increases up and right

• Increases down and left

• Increases up and left

• Increases down and right

A student claims that nonmetals become more reactive as you move down and left on the periodic table. Use evidence from periodic trends to evaluate this claim.

• The claim is correct; nonmetals are more reactive down and left.

• The claim is incorrect; nonmetals are more reactive up and right.

• The claim is correct; nonmetals are more reactive up and left.

• The claim is incorrect; nonmetals are more reactive down and right.

If you are given several elements, what reasoning process would you use to predict which one is the most metallic?

• Select the element with the most protons

• Choose the element closest to the bottom left of the Periodic Table

• Pick the element with the highest electronegativity

• Select the element with the smallest atomic radius
