What are polar compounds?

Back

Polar compounds are molecules that have a partial positive charge on one end and a partial negative charge on the other, leading to an attraction to other polar compounds.

Front

What are nonpolar compounds?

Back

Nonpolar compounds are molecules that do not have distinct positive or negative ends, and they do not mix well with polar compounds.

Front

True or False: To classify means to arrange items into categories according to shared qualities or characteristics.

Back

True

What is a characteristic of nonmetal gases?

Back

Nonmetal gases typically have low boiling points and do not conduct electricity well.

Front

True or False: Nonmetal gases have a high boiling point and conduct electricity very well.

Back

False

Front

What is a property of metals?

Back

Metals are good conductors of heat and electricity.

Front

What is the difference between metals and nonmetals in terms of physical properties?

Back

Metals are usually shiny, malleable, and ductile, while nonmetals are often dull, brittle, and not malleable.

Front

What is an example of a nonmetal solid?

Back

Sample B, which is dull and brittle.

Front

What happens when polar and nonpolar compounds are mixed?

Back

Polar compounds do not mix with nonpolar compounds due to their different molecular structures.

Front

What is the significance of molecular polarity in chemistry?

Back

Molecular polarity affects solubility, boiling points, and interactions between different substances.
