The number of Valence electrons of an element is the same number as the element's group number. E.g. Hydrogen is in Group 1. Therefore it has 1 valence electron. Another e.g. Oxygen is in Group 6. Therefore it has 6 valence electrons.

As you go down a group (or family) on the Periodic Table, the number of valence electrons remains the same. As you go accross a row, the number of valence electrons increases by one for each element.

Moving down or up a group, you notice that the number of valence electrons remains the same. Only the principle energy level changes, increasing as one moves down the group.

What do you notice about the number of energy levels in an atom of an element in the period the element is in?

The atom of an element in the third period of the Periodic Table has 3 energy levels and so on. Also, atoms of elements in the same group have the same no. of valence electrons.


Which elements do you notice about the location of each element in each family?

Elements in the same column belong to the same family. The elements in the family also have the same number of valence electrons.


What do you notice with the number of valence electrons?

The number of valence electrons determine the chemical properties of a particular element. For example, elements in group 1 tend to donate its valence electron away to produce its stable +1 ion. It also explains the formation of -1 ions from group 17 elements (halogens).


What do you notice about the number of electrons in each valence shell of noble gasses?

You see that there are 8 electrons, which means that the shell is full. Thus, you observe that nobly gases rarely bond.
