Principal Quantum Number(n)
by Fatimah Adnan
1. Describes the SIZE of the orbital or ENERGY LEVEL (shell) of the atom.
2. Always integer and positive value (n=1,2.....).
3. When electron jump from
3.1. Low to high the electron can absorbing energy.
3.2. High to low the electron can emit energy.
4. As "n" increases , the number of orbital in a given shell as well their size get large ,higher value of "n" have higher energy.
