Fluorine has seven electrons. Fluorine will form covalent and ionic bonds.
Ionic- If it combines with any metal
Covalent- If it bonds with a non-metal
Two fluorine atoms are needed to form an ionic bond with calcium, as each fluorine atom will contribute one electron to satisfy calcium's two valence electrons.
Fluorine is an element. Its atoms are made of basically 3 fundamental particles (as is an atom of every other element just with different proportions) called electrons, protons and neutrons. Fluorine itself is a pure substance and contains no other particles except Fluorine atoms.
The number of valence electrons in cyclopentadiene C5H6 is 54. Carbon has 4 valence electrons and hydrogen has 1, giving a total of 30 for carbon atoms and 24 for hydrogen atoms.
Serine has five valence electrons. It has three valence electrons from the oxygen atom and one valence electron each from the carbon and nitrogen atoms in its structure.
B. Fluorine has the greatest attraction for electrons among the atoms listed. It has the highest electronegativity value on the periodic table.
Fluorine has seven electrons. Fluorine will form covalent and ionic bonds. Ionic- If it combines with any metal Covalent- If it bonds with a non-metal
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.
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.
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.
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.
Two fluorine atoms are needed to form an ionic bond with calcium, as each fluorine atom will contribute one electron to satisfy calcium's two valence electrons.
There are 15 electrons in phosphorus, 45 electrons from five fluorine atoms, and they make 60 electrons altogether.

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).
I believe you are talking about fluorine. If you are, F needs one more electron to gain a full shell.If you go to WikiAnswers for this information, that is counterproductive, because there is a much better way to do it. Look at the periodic table. Groups IA through VIIIA tell you what you need to know. IA has one valence electron, IIA has two valence electrons etc. Fluorine is in group VIIA and therefore has seven valence electrons. All atoms want eight, and thus fluorine is in need of one more.
