How many electrons does fluorine have how many electron shells how many electrons are needed to fill the valence shell?
seven electrons
Lithium Fluoride Fluorine has seven electrons of it’s own. Lithium gives up its one electron to make both atoms happy. So the fluorine atom has eight electrons, and a filled outer shell.
How many electrons are there in an atom of fluorine if it has 9 protons?
9 electrons
By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well.

What is the atomic number of fluorine-19?
9
Fluorine-19 has an atomic number of 9. The atomic number is equal to the number of protons in an element and can be identified on the periodic table….
What is the atomic mass of fluorine?
18.998403 u
Fluorine/Atomic mass
How many core electrons does a fluorine atom have the atomic number of fluorine is 9?
As an example, fluorine (F), has an atomic number of 9, meaning that a neutral fluorine atom has 9 electrons. The first 2 electrons are found in the first energy level, and the other 7 are found in the second energy level.
What element has 9 protons 9 neutrons and 9 electrons?
element fluorine
The element fluorine has 9 protons and 9 electrons.
What elements has 19 number of electrons?
So if you look for potassium (symbol K in the periodic table), you will find that it has the atomic number of 19. This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons.
What is the mass number and atomic number of fluorine?
Fluorine’s atomic number is 9 and its mass number is 19. Which of the following is true of fluorine? A) It contains 9 protons and 19 neutrons. B) It has no net charge when it has 19 electrons. C) It contains 9 protons and 10 neutrons. D) It is lighter than helium.
How many electrons are there in a neutral atom of fluorine?
The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Fluorine is 9. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
What is the valence shell of fluorine?
Completing a valence shell means that the element becomes an ion (unless a noble gas) and it’s electron configuration matches that of the nearest noble gas on the periodic table. Fluorine is nearest to neon which is 1s2 2s2 2p6, whereas fluorine is 1s2 2s2 2p5.
What is an isotope of fluorine?
Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Mass numbers of typical isotopes of Fluorine are 19.
