basic atomic structure

• 3 particles of the atom

  -PROTON

  -NEUTRON

  -ELECTRON
• RESPECTIVE CHARGES

  PROTON = POSITIVE

  NEUTRON = NO CHARGE

  ELECTRON = NEGATIVE
• ATOMIC NUMBER = Protons & Electrons
• Atomic mass - Atomic number = NEUTRONS
• Z is the atomic number (below)

  A is the atomic mass (upper)

• The number of protons in one atom of an element determines the atom's IDENTITY, and the number of electrons determines the charge of the element.
