First question
Possible, ask
What is the meaning that the total number of electrons that orbit the energy levels in the nucleus of atom of the element fluorine equal to (9)

Please reply

[barbie]

The idea is not pretty for you and I put this topic for the purpose of assistance
Generally thanks

Thank u so much
Best wishes for all

that mean the first energy level takes 2 and the second takes 7 so the element need 1 electron to complete tha last energy level then florine+1 and also that mean the number of brotons inside the nucleus = 9 and the atomic number = 9 and the nucleus number = 18 please if my answer wrong try to help me to find the right answer
thanks

I did not mean the electronic distribution, but my question is What is the meaning that the total number of electrons that orbit the energy levels in the nucleus of atom of the element fluorine equal to (9
And, therefore, wrong answer
