Atomic number of Fluorine is 9.Mass number of Fluorine is 19.
Fluorine is a non metal element. Atomic mass number of it is 19.
Fluorine is a non metal element. Mass number of it is 19.
In a neutral atom of fluorine, there are 9 electrons. The number of neutrons varies with an isotope's mass number.
Mass number = 19, Atomic number = 9
Answer is in the question itself. 19. Because atomic mass is nearly equal to the mass number of the atom. Mass number is always a round number that is natural number. The proton code for fluorine atom is 9. Mass number is the total number of protons and neutrons. So for mass number 19, the number of neutrons will be 19 - 9 = 10.
Symbol - F Atomic Number - 9 Mass Number - 19
The weight (mass) of an atom with 9 protons will vary depending on the number of neutrons. 9 protons defines the atom as fluorine (F), and it can have 10 protons, making the mass 19 amu, or it can have a mass of 14 amu up to 31 amu, but the only stable isotope is the one with a weight (atomic mass) of 19 amu.
Fluorine is a metal element. Atomic Mass of it is 19.
9
The mass in grams of one fluorine atom is 18.998 grams per mole. Fluorine is a gas that has the atomic number of 9.
subtract the atomic number by the Atomic Mass, and that is the answer. if its a neutral atom, there are probably the same number neutrons as protons.
19.0
An atom of Fluorine has the atomic number 9 and the mass number 19 (rounded up). This means it has 9 electrons, 9 protons and (19-9) 10 neutrons. The proton and electron count are taken from the atomic number. The mass number - the atomic number gives the number of neutrons.
