10
Fluorine-19 has 9 protons, 10 neutrons, and 9 electrons.
There are 9 electrons in the atom without a charge, . The Fluorine ion (F -), has 10 electrons.
The atomic number of fluorine is 9. So it has 9 protons and 9 electrons. Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number F-19 has 10 neutrons
Fluorine belongs to the 7th Group of the periodic table - the halogens. It has --> 9 Protons 10 Neutrons 9 electrons in the atomic state. Also - it's oxidation state (valency) is (1-) or (7+) It has 7 electrons in it's outer most shell.
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.
9
Fluorine-19 has 9 protons, 10 neutrons, and 9 electrons.
In a fluorine atom: 9 protons, 10 neutrons, and 9 electrons.
There are 9 protons and 9 electrons in a fluorine atom The only stable isotope has 10 neutrons
A fluoride ion (F⁻) has gained an extra electron, giving it a -1 charge. Fluorine has an atomic number of 9, meaning it has 9 protons. Therefore, a fluoride ion has 9 protons and 10 electrons.
In a fluorine atom: 9 protons, 10 neutrons, and 9 electrons.
There are 9 electrons in the atom without a charge, . The Fluorine ion (F -), has 10 electrons.
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.
Fluorine has 9 protons and 9 electrons. The number of protons determines the element's identity, while the number of electrons is equal to the number of protons in a neutral atom.
Fluorine, F, has the atomic number 9. Atomic number is the number of protons, so fluorine atoms have 9 protons in their nuclei. In a neutral atom, the number of protons and electrons are equal. So a neutral F atom will have 9 electrons.
The atomic number of an element tells you how many electrons there are and how many protons there are.
Number of neutrons = Mass number - atomic number = 23 - 9 = 14
