  • Well there can only be 2 electrons in the first energy level, and only 8 in the second energy level. That means fluorine has seven electrons in it's second energy level. So the answer would be C. 7 electrons.

  • First shell can accomodate 2 electrons, while the second one can hold 8. But since F has 9 electrons, its second shell holds only 7 electrons, which is the answer to this question. Hope this helps!
