For each Element we are given:
Atomic Number – the number of protons in the nucleus

Chemical Symbol – letters that represent a certain element

Element Name – full name of the element


Atomic Mass – the weight of the atom (found by adding the number of protons and neutrons)

“Matter can be made up of just one kind of atom or different kinds of atoms joined together”

Molecules may have very different properties than the elements that they are made of

Example:

Sodium is a very reactive type of metal that explodes in water

Chlorine is a poisonous gas

Together they bond to form Sodium Chloride… or Salt
