What things are made of matter?
EVERYTHING
What does the atomic number tell you?
The number of protons / electrons an element has
What particles make up the nucleus of an atom?
Protons and Neutrons
What is a molecule?
Two or more atoms bonded together
What do the arrows represent in a food web?

Draw the density of molecules in a solid and in a gas
[higher density] = solid
[lower density] = liquid
Elements get bigger as you move right/down the table. The element number increases
What are the charge of Electrons, Neutrons, Protons?
Electrons- Negative (-1)
