An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
The total number of electrons found in the valence shell of a Halogen in the ground state is 7. The Halogens which are reactive nonmetals are in Group 17.
A fluorine atom in the ground state has 7 valence electrons.
A fluorine atom in the ground state has 7 valence electrons.
Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.
i think it has the same number of valence electrons
Fluorine has 7 valence electrons, however, Fluoride (F-) is an anion with a negative charge, giving it one more electron, bumping the number of valence electrons to 8.
Fluorine's atomic number is 9. Thus, neutral fluorine has 9 protons and 9 electrons. It's total configuration then is 1s2 2s2 2p5, so its valence configuration is 2s2 2p5.
A fluorine atom in the ground state has 7 valence electrons.
Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.
7 valence electrons
The number of valence electrons is seven.
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
i think it has the same number of valence electrons
The total number of valence electrons in Boron's ground state is 2
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
Fluorine has 7 valence electrons, however, Fluoride (F-) is an anion with a negative charge, giving it one more electron, bumping the number of valence electrons to 8.
Fluorine has 7 valence shell electrons. If it has a formal charge of (-1) that means that it has 8 non bonding electrons. Its atomic number is 9 therefore the fluorine anion (F-1) has 8 electrons and 9 protons.
2 valence electrons are in an aluminum atom in the ground state.
in a normal F- ion there are 10 electrons total (but 8 in the outer energy level)
