Group 3: Sc,Y,La, Ac

I have finally begun on the smaller groups – and have stitched the first element which doesn’t have an i in it’s name: Lanthanum.

gruppe/group 3

As you can see valence electrons begin to be in more than just one orbital per element (remember I illustrate them with the light coloured pearls).

Lanthanum and actinium gives the following groups, which are next in my stitching plan, their names: The Lanthanides and the Actinides.

Below here is a picture of the progress so far.  The ruler has cm as unit and i added to give you an idea of the size.
