(3) Atoms of different elements are different. (4) Atoms of different elements join together to make compounds. In the late 1800’s, J. J. Thomson discovered that atoms were made of smaller particles. He discovered the electron and devised the “chocolate-chip cookie” model of the atom....
The properties of elements are responsible for their physical state at room temperature: they may be gases, solids, or liquids. Elements also have specific chemical reactivity, the ability to combine and to chemically bond with each other.
