3. Bohr Model and Electron Transition
Maximum electrons per shell: 2n^2 [n = shell/orbit number (1,2,3,4,... i.e., K,L,M,N)]
Photon energy for electron transition: E = hν = E_f - E_i [E = photon energy, h = Planck's constant, ν = frequency, E_f = final energy level, E_i = in
4. Atomic Number, Mass Number and Nucleons
Atomic number = number of protons = number of electrons
Mass number (A) = number of protons(Z) + number of neutrons(n)
