A substance that cannot be broken down into simpler substances by chemical means.

A substance that consists of two or more types of atoms chemically bonded together.

A mixture of two or more substances.

A substance that can be separated into simpler substances by physical means.

What is the primary difference between an element and a compound?

Elements consist of only one type of atom, while compounds consist of two or more types of atoms chemically bonded together.

Elements are pure substances, while compounds are mixtures.

Elements can be broken down into simpler substances, while compounds cannot.

Elements are found only in nature, while compounds are man-made.

Which statement is true about the diagram above?

Sample 2 and 3 have the same properties.

The samples all have the same properties.

The samples all have different properties.

Sample 1 and 3 have the same properties.

Which of the following statements are true about compounds?

Compounds are made up of two or more different elements combined chemically in a fixed ratio.

Most matter in the universe exists in the form of compounds.

Compounds can be broken down into elements by chemical means.

Compounds can be separated into simpler substances by physical means.

Which of the following statements about the properties of compounds and their component elements is correct?

The properties of a compound are different from those of its component elements.

The properties of a compound are the same as its component elements.

Compounds are always gases at room temperature.

Compounds cannot be broken down into elements.

The diagram above shows the repeating groups of atoms that make up two samples. Both samples are green gases at room temperature. Will the other properties of the two samples be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)

The other properties will be the same because the repeating groups of atoms that make up the two samples are the same.

The other properties will be different because there are more repeating groups of atoms in Sample 2.

The other properties will be the same because both samples are green at room temperature.

The other properties will be the same because both samples are gases at room temperature.

This is a compound because...

It is represented with a chemical formula and has more than 1 different element.

It is Represented with a symbol and has only 1 element

It is Represented with a chemical formula and has only 1 element
