LiF is an ionic compound. The dot structure is shown with the Li atom with a 1+ superscript written with a plus sign to an F atom that has four pair of dots. The F atom will be enclosed in brackets with a 1- superscript.
The I is the central atom because it has the lowest electonegativity between iodine and fluorine. Each fluorine atom is bonded to the I with a sigma bond (single bond), and each fluorine atom has 3 lone pairs of electrons. The I also has one lone pair. The electron shape of this molecule is octahedral, because of the 6 electron regions-- 5 bonds, and one lone pair on the I-- and its molecular shape is square pyramidal because the lone pair is not included. This comes out to a total of 42 electrons, and a formal charge of 0 on each atom.
It is F with two dots on the top, two dots on the bottom, two dots on one side and 1 dot on the other side. That's a total of 7 dots (electrons), and that is the Lewis structure for fluorine (F).
For fluorine: 8 dots.
Although Excel checks that the formula has the correct structure, it does not check that the formula contains the correct values or cell references.
Louis dot structure should be: i.. :F: ii' ignore the i's i needed to move the dots over.
F3- does not form a Lewis structure because F (Fluorine) has 7 valance electrons. F3 totals 21 valance electrons +1 for the - charge for a total of 22. However when you attempt to bond 3 F atoms together in a Lewis structure there is only space for 20 valance electrons. This is not a problem for atoms like Br or I because they can fit those extra electrons in the near by d orbital. Fluorine being a period 2 element does not have a d orbital and can not form a F3- Lewis structure. -JCS
The Lewis structure for OF2 is:.. .. ..:F-O-F:'' '' ''We know that this is the best structure because the formal charge on each atom is 0, and the overall charge of the molecule is 0. Even without formal charge calculations we can predict this structure because we know that Halogens, such as Fluorine, never form double bonds.
The Lewis structure of fluorine contains 9 electrons, which 7 of them are valence. This means the letter F will be in the middle with 7 dots surrounded it, which would represent the 7 valence electrons.
For fluorine: 8 dots.
For fluorine: 8 dots.
CHCL3
The correct Lewis Structure for the oxygen atom will be an 'O' with two dots above and below, with one dot on the left and on the right sides.
I tried but I suck at chemistry

O=N=F Fluorine has 6 dots or electrons, oxygen also has 6, and nitrogen has 2.

No, SF6 doesn't. If you draw out the Lewis structure, all 6 fluorine atoms have to connect to the sulfur.
