Understanding the Periodic Table

What is the primary distinction between metals and nonmetals on the periodic table?

• Metals are non-reactive, nonmetals are reactive.

• Metals have higher melting points than nonmetals.

• Metals are gases, nonmetals are solids.

• Metals are on the left side, nonmetals on the right.

Which group in the periodic table is known as the alkali metals?

• Group 2

• Group 7

• Group 0

• Group 1

What happens to the reactivity of alkali metals as you move down Group 1?

• Reactivity decreases.

• Reactivity fluctuates.

• Reactivity increases.

• Reactivity remains the same.

What is the general reaction of alkali metals with water?

• Metal + Water → Metal Chloride + Hydrogen

• Metal + Water → Metal Hydroxide + Hydrogen

• Metal + Water → Metal Oxide + Hydrogen

• Metal + Water → Metal Hydroxide + Oxygen

Which of the following is a property of halogens?

• They are colorless gases.

• Their reactivity increases down the group.

• They are unreactive.

• They are involved in displacement reactions.

What is the state of bromine at room temperature?

• Gas

• Plasma

• Liquid

• Solid

In a displacement reaction, which halogen can displace another?

• Displacement depends on temperature.

• A more reactive halogen displaces a less reactive one.

• A less reactive halogen displaces a more reactive one.

• Halogens cannot displace each other.

Why are noble gases used to transport reactive substances?

• They are highly reactive.

• They are cheaper than air.

• They are colorless.

• They do not react with other substances.

What happens to the boiling point of noble gases as you move down Group 0?

• It remains constant.

• It increases.

• It fluctuates.

• It decreases.

Which noble gas is commonly used in advertising signs?

• Argon

• Krypton

• Helium

• Neon
