Identify that each orbital can contain only two electrons
Placement of electrons:
- Maximum number of electrons a principal energy level can hold = 2n2
- Every shell apart from n=1 has a number of energy sublevels or sub-shells with slightly different energies
- Number of subshells in a shell = To principal quantum number of the shell
- g n=3 has three subshells
- Unlike Bohr model, quantum mechanical model shows precise location of electron with specific energy cannot be known
- Instead linked to probability
- Region of space through which an electron of given energy may move = Orbital
- Each Orbital can hold a maximum of two electrons
