Atoms #1

An atom's atomic number tells you...

• Both the number of protons and electrons an atom has
• Just the number of protons an atom has
• Just the number of electrons an atoms has
• It's on the periodic table

How do you find the number of neutrons an atom has?

• Atomic mass - Atomic number
• Atomic number - Atomic mass
• Protons - Electrons
• Protons + Electrons

all matter is made of what 

• energy 
• atoms 
• electrons 
• compounds
