Kugelwolkenmodell max. 4 Wolken oder mehr?

Hallo,

ich schreibe morgen eine Chemie Arbeit und lerne gerade das Kugelwolkenmodell. Jedoch gibt es eine Sache die ich nicht verstehe. Im Unterricht meinte meine Lehrerin, dass die K-Schale 1 Wolke hat und die anderen Schalen enthalten max. 4 Kugelwolken. Jedoch steht im Internet was anderes und zwar das jede Schale mehr Wolken enthält, also 1 Wolke 4 Wolken 9 Wolken 16 Wolken… Ich weiß jetzt aber nicht was richtig ist oder ob ich da was falsch verstanden habe. Kann mir da jemand weiterhelfen?

What your teacher says and writes in lessons is crucial for work.

The ball cloud model is a strong simplification for main group elements. It allows binding conditions and spatial orientation of bonds to be represented and explained in simple elements. So it’s not bad. What you have learned is therefore O.K.: 2 /4 ball clouds.

However, it is replaced by more sophisticated models when the demands increase.

The clouds are called orbitals, but apart from that:

The shells actually have 1, 4, 9, 16 etc. Orbitals, but they are not clean from row to bowl for bowl filled with electrons.

The outer shell, which is interesting for the ball cloud model, only covers 4 clouds from the 2nd. What happens later in the transition metals can hardly be described in any case with the spherical cloud model.
