Fluorine is a non metal element. Atomic number of it is 9.
The atomic number of fluorine is 9.
nine
Nine (9).
Fluorine is a meta element. Atomic number of it is 9.
The atomic number of an element is equal to the number of protons in its nucleus. Given that the element has 9 protons, its atomic number is 9. Therefore, the element in question is fluorine (F), which has an atomic number of 9.
Fluorine.
An atom's atomic number gives us its number of protons. Fluorine's atomic number is 9. Thus, it has 9 protons.
The atomic number of fluorine is 9. So there are 9 protons
Neutrons have the same mass as a proton but lack an electrical charge. The number of neutrons can be found by subtracting the atomic number, or number of protons in the atom, from the atomic weight. This is calculated this way because the atomic weight represents both the number of protons and neutrons. Fluorine's atomic number is 9 and its atomic weight is 18.998, so 18.998-9= 9.998. Consequently, 9.998 is fluorine's number of neutrons.
Virtually 100% of fluorine atoms have 10 neutrons. (Wikipedia)
if u mean in the nucleus of fluorine then you can figure this out for yourself... its really simple considering that the electrons are the decimals so really all you have to do is subtract the atomic number (9) from the atomic mass (18) on the periodic table... so here it is: 18-9=9
Fluorine-19 (not "flourine-19) has an atomic number of 9 and therefore has 9 each of protons and electrons. The number of neutrons is found by subtracting the atomic number from the atomic mass number: 19 - 9 = 10 neutrons.
