Metals and Their Properties

What advantage do metals offer in terms of malleability and ductility?

• Metals can be easily hammered into sheets without shattering and stretched into wires without snapping.

• Metals can conduct electricity and are highly reactive.

• Metals are rare and difficult to find in nature.

• Metals have a low metallic character and can form ionic bonds.

Why are familiar metals like iron and silver more commonly used for crafting tools?

• They are easier to find in nature compared to other metals.

• They have a high metallic character and can form covalent bonds.

• They are highly reactive and conduct electricity well.

• They have a low metallic character and are safe to handle.

What is the main reason low-reactivity metals are useful?

• They occur naturally in forms easy to work with.

• They have a high metallic character and can form metallic bonds.

• They are highly reactive and can form ionic bonds.

• They have a low metallic character and are safe to handle.

Why did NASA choose beryllium for the James Webb Space Telescope?

• Beryllium is lightweight and holds its shape in frigid temperatures.

• Beryllium is highly reactive and conducts electricity well.

• Beryllium is rare and difficult to find in nature.

• Beryllium has a low metallic character and can form covalent bonds.

What is the main difference between metal and nonmetal atoms in terms of stealing electrons?

• Metal atoms usually give up their own electrons, while nonmetal atoms steal electrons from other atoms.

• Metal atoms and nonmetal atoms both steal electrons from each other.

• Metal atoms and nonmetal atoms both share their electrons.

• Metal atoms usually steal electrons from other atoms, while nonmetal atoms give up their own electrons.

What type of bond occurs when two metal atoms bond?

• Metallic bond

• Ionic bond

• Covalent bond

• Nonmetallic bond

What property of metals allows them to conduct electricity?

• Delocalized electrons

• Ionic bonds

• Covalent bonds

• Nonmetallic character

Why are some metals too malleable to use in tool-making?

• Their atoms move around too easily, making them too soft.

• They have a high metallic character and can form metallic bonds.

• They are highly reactive and conduct electricity well.

• They have a low metallic character and are safe to handle.

What is an alloy?

• A mixture of metals or a metal mixed with a small amount of a nonmetal.

• A type of covalent bond between two nonmetals.

• A type of ionic bond between a metal and a nonmetal.

• A pure metal with high malleability and ductility.

Why is carbon steel used for making skyscrapers, bridges, and kitchen knives?

• Carbon steel is harder and less malleable than pure iron.

• Carbon steel is highly reactive and conducts electricity well.

• Carbon steel is rare and difficult to find in nature.

• Carbon steel has a low metallic character and can form covalent bonds.
