The last one is NOT true.
A good example is water. Pure water contains hydrogen and oxygen in a fixed atomic ratio of 2:1. However, at room temperature and pressure water is a non-flamable colorless liquid, and very different from its constituent elements. Hydrogen and oxygen, which under the same coditions are gasses, and in the case of hydrogen, highly flamable.

This sounds like homework. This is in your textbook and/or your notes.
