What are Subatomic Particles?
There are three subatomic particles ( proton, electron, and the neutron )
There are three subatomic particles ( proton, electron, and the neutron )
Protons:
Electrons:
Neutrons:
- sympol is a p+
- they have a positive charge
- Relative mass is 1
- Actual mass ( in grams ) ( 1.67 x 10^-24)
Electrons:
- symbol is e-
- has a negative charge
- relative mass 1/1840
- Actual mass ( in grams ) ( 9.11 x 10^-28)
Neutrons:
- its symbol is n o
- has no charge
- relative mass 1
- Actual mass ( in grams ) ( 1.67 x 10^-24)

Structure of the Atom
- Positive charge
- most of the volume ( takes up most of the space )
- Where electrons are found
- 2 regions
- Nucleus ( has protons and neutrons, also makes up most of the mass )
- Positive charge
- Electron cloud
- most of the volume ( takes up most of the space )
- Where electrons are found

Count The WHAT?
It's pretty easy
It's pretty easy
- Atomic number ALWAYS equals the number of protons
- Mass number is the number of protons + the number of neutrons
Are the mass number and Atomic number different?
YES
The mass number is the number of protons + neutrons ( its the weight of the atom ) While the Atomic number is how many protons are in the atom, you will still need to add neutrons to this in order to recieve the mass number.
What's an Isotope?
Isotopes have the same number of protons but a different number of neutrons.
What does amu mean?
A. atomic
M. mass
U. unit
