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.
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.
A fluorine atom in the ground state has 7 valence electrons.
In a neutral atom of fluorine, there are 9 electrons. The number of neutrons varies with an isotope's mass number.
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.
Chlorine 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
A fluorine atom in the ground state has 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.
Oxygen (O) has 6 valence electrons and fluorine (F) has 7 valence electrons. In OF2, there are a total of 18 valence electrons (6 from oxygen and 2 x 7 from fluorine).
The total number of valence electrons in Boron's ground state is 2
The PF6⁻ ion consists of one phosphorus (P) atom and six fluorine (F) atoms. Phosphorus has 5 valence electrons, and each fluorine atom has 7 valence electrons, contributing a total of 42 electrons from the six fluorine atoms. Adding the 5 from phosphorus and accounting for the extra electron due to the negative charge, the total number of valence electrons in PF6⁻ is 48.
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?
The total number of valence electrons in OF2 is 18. This is calculated by adding the number of valence electrons for each atom (O has 6 and F has 7) and considering that there are two fluorine atoms linked to one oxygen atom in the molecule.
An atom of aluminum in the ground state has 3 electrons in its valence shell. Aluminum has an electron configuration of 2-8-3, so its valence shell is the third shell, where the last 3 electrons reside.
The total number of electrons in a neutral fluorine atom is 9, which is the atomic number of fluorine.
