The Periodic Table and Atomic Structure

The rules that govern bonds between atoms and molecules can be quite tricky. It may be worthwhile to review the chapters involving atomic structure and the periodic table/trends before you tackle the material presented here.

Before we leave the subject of atomic structure and the periodic table, we need to examine one other observation the existence of atoms of the same element that have different masses. 

In 1921, Bohr returned to the problem of atomic structure and the periodic table. In 1922 and 1923, he announced a new, improved version of the electronic periodic table. Again he employed the aufbauprinzip to build up successive atoms in the periodic table, but this time he used two quantum numbers , the principal quantum number, and fe, the second or azimuthal quantum number, which later became labeled as i (table 7.3). The second quantum number had recently been discovered by Arnold Sommerfeld, a theoretical physicist in Munich.
