- 1Structure of Atom-Made up of small subatomic particles; protons, neutrons, electrons
PROTON: + charge, # of proton is ATOMIC NUMBER,
NEUTRON: no charge, neutral
proton + neutron= nucleus (central part of atom)
ELECTRON: - charge
electron= moving rapidly white surrounding nucleus - 2Structure of Atom (visual)
- 3Mass number? Atomic number?Mass number (A): # of protons&neutrons in nucleus of atom
Atomic number (Z): # of protons&electrons in atom - 4Label diagram of mass and atomic number
- 5Definition of Isotopes2/more atoms with the same number of PROTONS but different number of NEUTRONS thus different mass
e.g: carbon-12, carbon-14 - 6Electron arrangements1st shell: 2 electrons
2nd shell: 8 electrons
3rd shell: 8 electrons
