118 Atomflowers of the periodic table

Atoms exist of a positive charged nucleus with negative charged electrons orbiting around them.

The nucleus exist of positive charged protons and neutral neutrons. When there are as much protons as electrons the atom is neutral. Protons and neutrons exist of up en down quarks.

According to Pauli's exclusion rule: electron orbitals can consist only 2 electrons (spin up (white) and spin down (black))

In real 3D atoms there are many different shapes of these orbitals.
In the 2D atomflowers only 4 of these shapes are used: sphere (s), 2 lobbed (p), 4 lobbed (d) and 8 lobbed (f) They are the petals.

By rotating (1s, 3p, 5d, 7f) these petals they form the shells. According to Hund's rule: when all the petals of an shell have one white electron they can get a black electron. When al petals of that shell have 2 electrons (white and black) the shell is filled. Giving these shells seven different colours give the atomflowers their colourfull appearance, (see atom 58: Cerium).

The biggest atoms are on the left side and the smallest on the right side.

Atomflowers are beautifull coloured 2D simplifications of not coloured 3D atoms.
