A vast number of matter is like that...air is the most common example.
any substance made of two or more substances is either a compound or a mixture - if its a compound the atoms are chemically bonded together in a fixed ratio
It is a mixture.

they are not chemically combined. some examples are: kool-aid salad

When matter contains only one species of atom (same number of protons in nucleus of each), it is called an element.Related Information:Each element is made of atoms that are essentially the same, with the same number of protons in the atomic nucleus. An element may have stable forms with varying numbers of neutrons, and these are called isotopes.Elements are classified as pure substances, a type of matter that cannot be chemically separated into other components. Matter that consists of only one type of atom (for instance iron, Fe) is called an element. Matter that consists of two or more types of atoms, chemically combined (for instance table salt NaCl, sodium and chlorine combined) is called a compound

Yes: it's a substance with two types of atoms that are chemically combined- copper and oxygen.

In general, when a chemical bond forms between two or more atoms, it creates a molecule.
An element is composed of only one type of atom. Compounds are composed of different types of atoms (different elements) that are chemically combined.
