Atomic Structure
The 3 subatomic particles
Neutron
Electron
Proton
Mass = 1 amu
Position = in nucleus
Charge = +1 positive
Mass = 1 amu
Position = in nucleus
Charge = 0 neutral
Mass = 0 amu
Position = out nucleus
Charge = -1 negative
Electron arrangements
2,8,8.....
E.g. Carbon's electron arrangement would be 2,4
E.g. Potassium's electron arrangement would be 2,8,8,1
Isotopes
Two atoms of the same element with different mass numbers
Or - atoms with the same number of protons, but different number of neutrons
Ions
A charged atom
Formed by the gain or loss of electrons
Nuclide notation
The C represents the element Carbon
The 6 is the atomic number, that symbolizes how many protons that are present
The top 12 is the mass number, you get that by adding the number of protons and neutrons, so the number of neutrons present must be 6
