Fluorine is a halogen gas. It has 19 protons in a single atom.
The atomic number of fluorine is 9. So there are 9 protons and 9 electrons. The number of neutrons depends on the isotope. F-19 isotope has 10 neutrons.
A fluorine atom has 9 electrons and it has the only isotope, fluorine-19.
beryllium has 4 protons. helium has 2 protons
There are 19 protons in the potassium atom.
beryllium has 4 protons and helium has 2 protons
Fluorine has 9 protons.
Fluorine has 9 protons.
There are 9 protons in the element fluorine.
The atomic number of fluorine is 9. So there are 9 protons
Each fluorine atom has 9 protons.
There are 9 protons in the element fluorine.
9
An atom's atomic number gives its number of protons. Fluorine's atomic number is 9. Thus, fluorine has 9 protons.
There are 9 protons and 9 electrons in a fluorine atom The only stable isotope has 10 neutrons
9
All isotopes and ions of fluorine have nine protons.
The number of protons is equal to the atomic number. Fluorine's atomic number is 9, so Fluorine has 9 protons.
