In Chapter 6 we discussed quantum mechanics and how electrons arrange themselves in atoms. In addition to explaining the electronic properties of the atom, quantum mechanics can also explain the arrangement of elements in the periodic Table.
7.1 Development of the Periodic Table
The periodic table is broken down into two main groups. Group “A” or the main group elements, and Group “B” or the transition metals
7.1 Main Group Elements and Transition Metals
Periodic Trends allow chemists to generalize properties of atoms and they will be a big help in explaining the concepts of chemical bonding in the next chapter. The first trends we will investigate are atomic and ionic radii.
