O The atoms are not chemically bonded, and there is no set ratio for how the atoms can combine together.
The atoms can only combine in fixed ratios, and they can only be separated by a chemical change.
O The atoms do not retain their individual chemical properties, and they can be separated by physical means.

Answer 1

The atoms can only combine in fixed ratios, and they can only be separated by a chemical change.

Step-by-step explanation:

A compound is where two or more elements are chemically joined. This means that the atoms lose its individuals properties and have different properties from the elements it is combined with. Salt and sugar are simple examples of this.

Once chemically joined, a compound cannot be physically separated like picking off raisin off a raisin cookie. It must be separated through another chemical change.

There is also a fixed ratio that atoms combine due to the nature of electrons and individual elemental properties.
