Atom
Atomic Models
Bohr Atomic Model
-Electron assumed to resolve arund the atomic nucleus in discrete orbitals
-Position any particular electron
is more or less well defined in terms of its orbitals
-Energies of electron are quantized
-Electron may change energy, by make a quantum jump either to higher energy or lower energy
-allowed electron energies associated with energy level
-Electron tend to occupy lowest energy state
-Describe electron position & energy in atom
Wave-Mechanical Model
-Wave-like characteristics
-Particle-like characteristics
-not a partical moving in discrete orbital
-Electron cloud
Mass(g) | Charge(C)
Proton 1.673x10^-24 | +1.602x10^-19
Neutron 1.675x10^-24 | 0
Electron 9.109x10^-28| -1.602x10^-19
