Carbon is the middle atom, there are no double bonds you just add the 4 other atoms around it in a tetrahedral structure (if you haven't done this yet don't worry about it)

CH2F2 is a hydrofluorocarbon. If you put the carbon in the middle and put one valence electron each on the left, right, top, and bottom, then bond the H's and F's to each of those four sides, you will find that your Lewis structure works. Remember, H has 1 valence electron and F has 7. Carbon will need to share to get 8, along with the fluorines. H only needs 2. All your bonds will be single covalent, with unshared electrons on the flouorine sides, making it a polar covalent molecule.
The Lewis dot structure of CH2F2 shows C as the central atom with an H attached to each side and an F attached to each side. Each H and F atom has one dot around it representing a valence electron.
The dot structure arranges the electrons around its central nucleus.
A synonym for Lewis diagram is Lewis structure. It is a schematic representation of the bonding between atoms in a molecule and the arrangement of valence electrons around atoms.
The nuclues.
There are 16 dots in the Lewis Dot Structure of H2Se. Each hydrogen atom contributes 1 dot and selenium contributes 6 dots.
The difference between the Lewis dot structure and the structural formula is that the formula only shows the bonds that have formed whereas the dot structure shows all the valence electrons, including lone pairs, in that molecule.
Lewis dot formula
No, not exactly. It is an ionic compound so it would not have a Lewis dot structure. However, the carbonate anion, CO3^2- does have a Lewis dot structure.
A synonym for Lewis diagram is Lewis structure. It is a schematic representation of the bonding between atoms in a molecule and the arrangement of valence electrons around atoms.
The Lewis Dot Structure for Ununoctium (Uuo) would have 8 valence electrons represented as dots surrounding the atomic symbol. However, as Ununoctium is a synthetic element and its chemical properties are not well-known, its Lewis Dot Structure is not commonly depicted.
The Lewis dot structure for Ce (cerium) will have 4 dots representing the valence electrons of cerium. Cerium is in group 3 of the periodic table, so it has 3 valence electrons. The symbol for cerium is Ce and you would place one dot on three sides of the symbol.
The nuclues.
There are 16 dots in the Lewis Dot Structure of H2Se. Each hydrogen atom contributes 1 dot and selenium contributes 6 dots.
Will this link help you?, it is quite impossible to draw a Lewis dot structure in this simple text editor. See related links.
The Lewis dot structure for citric acid (C6H8O7) shows three carboxylic acid functional groups. The Lewis dot structure for baking soda (NaHCO3) shows a sodium cation (Na+) bonded to a bicarbonate anion (HCO3-).
The difference between the Lewis dot structure and the structural formula is that the formula only shows the bonds that have formed whereas the dot structure shows all the valence electrons, including lone pairs, in that molecule.
Absurd Question
The Lewis dot structure for BeO consists of one beryllium atom bonded to one oxygen atom. Beryllium has 2 valence electrons and oxygen has 6 valence electrons. The two atoms will form a bond by sharing two electrons, resulting in a stable structure with a full outer electron shell for both atoms.
The Lewis dot structure for vinegar, which is a molecule of acetic acid (CH3COOH), consists of carbon with four valence electrons (C), two hydrogens with one valence electron each (H), one oxygen with six valence electrons (O), and one more oxygen with six valence electrons. Each hydrogen bonds with the carbon, the oxygen atoms form double bonds with the carbon, and the remaining oxygen accepts a lone pair from carbon.
