DNA structure. This will be the central atom s that the other, more electronegative atoms, are bonded around.
Note that hydrogen can never be a central atom as it can only make one covalent bond. Also, list any extra electrons due to the negative charge on the overall molecule and your expectations about the bonding capacity of each atom to reach the octet.
Note that we have four oxygen atoms that have to bond to the phosphorus. To do this add up all the valence electrons for each atom present. If there is no overall charge on the molecule, this number will represent the total number of valence electrons in the molecule. If there is a net negative charge on the molecule, add the additional electrons to the number of valence electrons for all the atoms present to calculate the total number of valence electrons in the molecule.
This molecule will exist as an anion. If the molecule has a net positive charge, subtract off the total positive charge from the number of valence electrons for all the atoms present and this will represent the total number of valence electrons on the molecule. This molecule will exist as a cation. You will see that you need to start with the center phosphorus. For phosphorus, we know that it will make 5 bonds in the expanded orbital format Table 5.
So start by drawing in those 5 bonds.
After this fill in the lone pair electrons for all of the atoms, until you reach a total of 32 electrons. Next, calculate the formal charges on each atom. Since three of the oxygens have a 1— charge and the other two atoms are zero, the overall charge on the molecule is 3—. The completed Lewis structure for phosphate should look like this: 4 Draw resonance structures as needed.
Thus, each oxygen surrounding the phosphorus should have equal opportunity to form the double bonded position. We have shown the double bond forming in the downward position, but it has an equally probable chance of forming with any of the other three oxygens. Thus, we can show the structure with the double bond position in all of the other possible conformations: In actuality, none of the resonance structures represent the true structure.

After a manuscript has gone successfully through the peer review process authors may be asked to upload individual graphic files separately.
Any diagram, graph, spectra, photograph or other type of illustration is presented in the manuscript as a figure. The designation scheme should be used primarily for reaction schemes. It is the authors' responsibility to provide figures at a sufficiently high resolution to ensure high quality reproduction in the final article.
The following guidelines must be considered when preparing figures and schemes: Figures and schemes are consecutively numbered with Arabic numerals in the order they are first cited in the manuscript text i.
Figure 1, Figure 2, etc. The legends of figures and schemes should be positioned directly below the corresponding graphic in the main manuscript rather than as part of the graphic file.
They should comprise the bold typed figure or scheme number followed by a colon, a detailed legend with up to words and optional, a concise title of 15 words maximum. Any legend should be comprehensible without reference to the relevant parts of the manuscript text. If a figure has several labeled parts a, b, c, etc.
Each figure or scheme should comprise only a single file.
Multi-panel figures with individual parts a, b, c, etc. Each figure or scheme must fit a width of 8. The maximum height is The image resolution of raster images should be at least dpi colored graphic or dpi black and white graphic. Figures and schemes should be cropped as closely as possible to minimize white space surrounding the graphic. The maximum file size should not exceed 10 MB to optimize online handling. Individual compounds must be numbered with boldface Arabic numerals in the order in which the compounds are first mentioned in the text.
Boldface lower case letters may be added to distinguish compounds that differ only in the identity of substituents. There is no charge for the use of color.
If a raster image is enlarged it will become fuzzy. To ensure that such images will be of high quality in the web and in the printed article a minimum of dpi colored graphic or dpi black and white graphic is required. By contrast, a vector image e. All lines of the image are sharp at any zoom. Structure Drawing Guidelines Chemical Structures should be prepared according to the guidelines given below.
