There are 9 protons and 9 electrons in a fluorine atom.
7
it has 9
9 electrons !
A neutral fluorine atom has the same number of electrons as protons. Fluorine has 9 protons, so it has 9 electrons.
Fluorine's atomic number is 9.. That means it has 9 positively charged protons per atom. To keep it neutral then, it must also have 9 negatively charged electrons per atom.
Look at the periodic table. What position does fluorine take on the table. What does the position tell you?
