Properties of M, NM, and SM

Front

What are metals?

Back

Metals are elements that are typically malleable, ductile, and good conductors of heat and electricity. They are mostly solid at room temperature and have high melting points.

Front

What are nonmetals?

Back

Nonmetals are elements that are usually dull, brittle, and poor conductors of heat and electricity. They often have low melting points and can be gases, liquids, or solids at room temperature.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals. They are semiconductors and are often used in electronics.

Front

What is malleability?

Back

Malleability is the ability of a material to be deformed under compressive stress, allowing it to be shaped into thin sheets without breaking.

Front

What is ductility?

Back

Ductility is the ability of a material to be stretched into a wire without breaking.

Front

What is conductivity?

Back

Conductivity is the ability of a material to conduct heat or electricity. Metals are generally good conductors.

Front

What is the state of most metals at room temperature?

Back

Most metals are solid at room temperature, with the exception of mercury, which is a liquid.

Front

What is the significance of aluminum's malleability?

Back

Aluminum's malleability allows it to be easily shaped into products like soda cans and airplane parts.

Front

What are the characteristics of nonmetals?

Back

Nonmetals are typically dull, brittle, and have low melting points. They are poor conductors of heat and electricity.

Front

How many known elements are there?

Back

There are over 100 known elements, not just about 65.
