7 as shown above.
A fluorine atom has seven valence electrons, as do all halogens.
A fluorine atom has 7 valance electrons. This can be identified by looking which group fluorine is located, which is group 7. However when the atoms get bigger this rule does not apply so easily.
A fluorine atom has 7 electrons in its outermost unexcited main energy level. This allows fluorine to achieve a full valence shell of 8 electrons by gaining one additional electron through bonding.
Xenon pentafluoride (XeF5) has a total of 8 valence electrons. Xenon (Xe) contributes 8 valence electrons, while each fluorine (F) atom contributes 7 valence electrons. The 5 fluorine atoms in XeF5 contribute a total of 35 valence electrons.
In IF3, iodine (I) has 7 valence electrons and each fluorine (F) has 7 valence electrons. Thus, the central iodine atom in IF3 is surrounded by 21 electrons from the three fluorine atoms (7 electrons each).
A neutral atom of fluorine contains 7 valence electrons.
A fluorine atom has seven valence electrons, as do all halogens.
Fluorine atom has seven valence electrons.
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
A fluorine atom has 7 valance electrons. This can be identified by looking which group fluorine is located, which is group 7. However when the atoms get bigger this rule does not apply so easily.
A fluorine atom can accommodate one more electron in its valence shell to achieve a full valence shell of 8 electrons.
There are 7 valence electrons in an NF3 molecule. Nitrogen has 5 valence electrons and each fluorine atom contributes 1 valence electron, totaling 3 electrons for the 3 fluorine atoms.
A fluorine atom has 7 electrons in its outermost unexcited main energy level. This allows fluorine to achieve a full valence shell of 8 electrons by gaining one additional electron through bonding.
The valence shell of a fluorine atom can hold a total of 8 electrons. Fluorine already has 7 electrons in its valence shell, so it can accommodate only 1 more electron to complete its octet and achieve a stable electron configuration.
Xenon pentafluoride (XeF5) has a total of 8 valence electrons. Xenon (Xe) contributes 8 valence electrons, while each fluorine (F) atom contributes 7 valence electrons. The 5 fluorine atoms in XeF5 contribute a total of 35 valence electrons.
In IF3, iodine (I) has 7 valence electrons and each fluorine (F) has 7 valence electrons. Thus, the central iodine atom in IF3 is surrounded by 21 electrons from the three fluorine atoms (7 electrons each).
Fluorine has 7 electrons in its outer shell, and it needs 1 more electron to complete its valence shell, which can hold a total of 8 electrons.
