Think about the next problem:
The main groups do not contain all elements. In da scheme with 7 rows and 8 coloms you can place a maximum of 7 x 8 = 56 elements. We know that there are about hundred different elements. What now?
To place the other elements, we must apply a more complete methode; for that, we need a closer look at the electronic structures.
You already knew the s- and the p-blocks, but you must know that al toghether there are s, p, d and f-blocks in the complete PT. Please read again the story about electronic structures in module 01.

example:
The atom of element Sodium has the following electronic structure in sublevels: 1s2, 2s2, 2p6, 3s1.

So, the outer sublevel of the Sodikum atom is of the type s and this means that the element belongs to block s, the first block of the complete PT.

Do you know the position of an element in the PT, than it is possible to say something usefull about the properties of this element.
