Hallo, die elektronen kre4isen ja nach dem borhscfhen atommodell um den atomkerbn, ich frage mich aber dabei wieso diese nicht in den atomkern stürzen da sie ja angezogen werden müssten von dem Kern oder ?

Loading...Hallo. Ich habe so Schwierigkeiten zu verstehen, wie genau das Lichtmuster am Intensitätsprofil zu stande kommt. Licht setzt sich zusammen aus verschiedenen Wellenlängen. Das Licht wird drch das Gitter aufgespalten und die Wellen hinter dem Gitter interferien nun miteinander. Jetzt hat man ja aber Wellen mit verschiedenen Wellenlängen. Es interferien jetzt doch also Wellen mit…
Hallo ich arbeite mich durch einen Vortrag (Physik Lk) über das Frank Hertz Experiment und bin an einer Stelle wo ich nicht weiterkomme. Das Atom was durch das elektron angeregt wird bzw das Hg-elektron wird in ein höheres Energieniveau gehoben. Im Internet steht, es sei von 6^1 S0 –> 6^3 P1 . ich habe keine…
Halli Hallo! Ich möchte gerne aus pvc rohren ein Slapaphone, wie das glaube ich genannt wird, bauen. Wie berechne ich nun die benötigte länge für verschiedene Töne? Am besten wäre es wenn ich eine excel Tabelle mache aber wie mache ich das? Danke schonmal im voraus? LG LurBanane
Hallo zusammen, mich würde mal interessieren, wie ein Elektriker einen Hausanschlusskasten wechselt? Ich meine die Leitung von den Stadtwerken lässt sich ja nicht abschalten, also müsste er ja unter Spannung gewechselt werden. Oder gehe ich falsch in meiner Annahme?
ich habe schon einen teil gemacht, aber ich weiß nicht wie ich auf den rest komme
The idea that electrons like planets circle around the atomic nucleus is just a model with which, although some can not explain all the properties. A circular electron would, for example, be subject to the centripetal force and thus radiate through its charge. It would lose energy and actually rush into the core.
Electrons can also be imagined as a wave around the core and only integer ratios are possible. The wave must be closed in itself, since a wave valley cannot meet a wave crest. This classification also explains the quantum leaps. The lowest possible energy of an electron is a simple wave and is already outside the core.

Why doesn’t the moon fall into the earth? Why doesn’t the earth fall into the sun?
That’s exactly what you can imagine with the electron. The attraction between the electron and the atomic nucleus acts as a centripetal force which holds the electron on its circular path. If this attraction force were not present, the electron would simply fly tangentially along a straight line instead of staying on a circular path.
[In essence, however, this is not really right, as the drill atomic model is not right. Instead of circular paths, the electrons are in certain quantum mechanical states, the orbitals, which are a little more complicated. But even if the first part of my answer is not entirely correct, hopefully it should be clear where your mistake of thinking lies.]
Do not miss a “not“?
Well recognized. Yes, there was a “not” missing. Thank you.
the earth is also attracted by the sun and does not fall into it. or the moon of the earth.
if the circulating speed is suitable for the central force, a stable circulating path results. the one object falls almost permanently around the other.
(if one penetrates deeper into the uterine, one sees that it is not so simple in the case of the atom due to the radiated electromagnetic radiation expected after classical physics and that the stability of the atom cannot be explained and the phenomena are explained only in the context of quantum mechanics. but as long as you don’t understand the simple case in the system erde-sonne (and from your question I conclude that doesn’t do), it’s meaningless to go so far)
The statement is in this sentence:
For thatElectronnot withCoreto makeUncertaintyand thePauli principle.
I am not able to explain it in simple words. The electron becomes faster and faster the closer it is at the core, this state is increasing energy. The relevant atomic model is the orbital model of quantum mechanics.
This is a complex question with an equally complex answer.

The short answer is that the drill atomic model is simply wrong.
The model is still used today, models explain certain aspects, no more. This is the meaning of models.
