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.
One atom of sodium and one atom of fluorine.
9
There will be 9 protons in a fluorine atom, but actually, there exists only fluorine-19.
Fluorine is an element, s an atom of fluorine contains only one element - fluorine. However, the fluorine molecule consists of two atoms of fluorine.
Fluorine has atomic number 9, which means it contains 9 protons in the atomic nucleus. A neutral fluorine atom also has 9 protons. Fluorine has only one stable isotope, which has 10 neutrons.
The number of protons is the same as the atomic number, which is nine in this case. If the atom is neutral, then the number of electrons will balance the number of protons, also nine in this case. Usually, the number of neutrons will vary with the isotope (atoms with a different number of neutrons) however, fluorine has only one natural isotope, 18F, with nine neutrons.See link below for more information on fluorine, as well as the related question below that will show you how to find the number of each subatomic particle in any atom.
Although there are 19 forms of fluorine, known as isotopes and an isomer, only one exists in significant quantities. It is 19F, meaning that it has an atomic mass of 19. The atomic number of fluorine is 9. Therefore, the number of neutrons in a nucleus of an atom of this isotope of fluorine is 10.
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
In a molecule of fluorine (F2), each fluorine atom shares one electron with the other, so each fluorine atom has a total of 8 electrons, with 7 of them in the outer shell.
Titanium-47 has 25 neutrons.
Technetium-98 has 55 neutrons.
