What is the significance of Earth's elements?
There are more than 100 that combine in a multitude of ways to make up all living and nonliving things
They have different chemical and physical properties
There must be a new substance formed as the result of a chemical reaction
density, boiling point, melting point,freezing point, and solubility
it will spread out indefinitely because it has no definite shape or volume
an atom
They have the same chemical and physical properties because they are made of the same element
