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
In a fluorine atom: 9 protons, 10 neutrons, and 9 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.
Fluorine has an atomic number of 9. This means that it contains 9 protons; each one having a +1 charge. Therefore, in order for fluorine to have a net charge of 0, it must also contain 9 electrons, because electrons have a charge of -1.
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
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 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
