Multiple Choice

Which of the following metals is most likely to react with cool water?

• Sodium

• Iron

• Gold

• Copper

Multiple Select

Which of the following statements about less reactive metals are correct?

• They react only with acids.

• They corrode easily.

• They do not react with cool water.

• Examples include zinc and iron.

Fill in the Blanks

The least reactive metals, such as platinum or gold, may only react with very

acids.

Open Ended

Explain how the periodic table can be used to determine the reactivity of metals.

Multiple Choice

Why are metals further down in a group usually more reactive?

• They have more energy levels, making it easier to remove an electron.

• They have fewer protons.

• They are heavier.

• They have smaller atomic radii.

Multiple Choice

As you move across a period in the periodic table, what happens to the reactivity of metals?

• It usually decreases.

• It usually increases.

• It stays the same.

• It fluctuates randomly.

Multiple Select

Which of the following elements exist as diatomic molecules in nature?

• Fluorine

• Chlorine

• Oxygen

• Sulfur

Multiple Choice

Which of the following statements best explains why highly reactive nonmetals tend to gain electrons when reacting with metals?

• They have large electron affinities.

• They have small atomic radii.

• They are good conductors of electricity.

• They have high melting points.

Open Ended

Explain how the reactivity of nonmetals changes within a group and within a period in the periodic table.

Fill in the Blanks

As the atomic number increases across a period, the electron affinity

and the nonmetal becomes more reactive.
