Shipping from China hidden costs?
I ordered something from China (I only noticed this after placing the order) Shipping was not included, so I have now paid a sum X (not very much) Could additional costs arise now? After all, shipping from China to Germany is certainly very expensive.
Does every system strive for a stable energetic state?
Are my statements true or correct? Reason (why something is formed): – The formed: representation of a more stable state. – Education: Energy is released. – Dividing the parts: Expenditure of energy to separate it. —– – Biological systems (e.g. cells, organisms) e.g. humans & food intake 1) Intake: Food 2) Goal: Generation of energy…
Electron acceptor or donor?

Unfortunately, I haven't made any progress with this task. Could you perhaps show me an easy way or a rule by which I can recognize this. Thank you in advance.
Atomic structure?

The question is what are nucleons? I know this is protons and neutrons Unfortunately, I don't know the answer to the second question? (See picture) Thank you.

How did Otto Hahn and Fritz Strassmann manage to bombard uranium atoms with neutrons? Where did they get these neutrons from?

Hi.
Calcium is in the second main group. In salt formation, the calcium emits the two external electrons and becomes Ca(2+).
In the case of fluorine, which is in the seventh main group, there is no electron to reach the electron octet. F(-).
So you need F(-) twice for a Ca(2+) so that the salt is calcium fluoride

and one more question: each fuel atom can absorb 3 electrons in order to achieve the noble gas configuration, so a nitrogen molecule 6 can electrons, or
That’s right. A nitrogen atom takes up three electrons, so two nitrogen atoms take up six electrons. The electrons take up not the molecule, but the two atoms of the molecule take three electrons. Example:
6 Na + N2 → 2 Na3N
You’re welcome.
thank you
