The expression for Bohr's radius of an atom is: (1) r= n 2 h 2 / 4 Π 2 me 4 z 2 (2) r= n 2 h 2 / 4 Π me 2 z 2 (3) r= n2h2/4 Π me 3
Each element has a unique number of protons. This unique number is known as the element's atomic number . All atoms of a given element have the same atomic number. For example:
