There are many ways to write a chemical formula, but the most common way is by following these steps (beware that different types of bonding are named in different ways)
1) Look at the charges for all listed elements or polyatomic ions and solve for neutrality (in other words, make sure that when you multiply the charges by the number of each and then add them together so it equals zero)
2) You may not have to look at the charges if it is a type IV compound in which case you can look at the greek prefixes and use those to figure out how much of each you need (just for reference: mono=1 but it is rarely used)
di=2 (sometimes bi)
tri=3
tetra=4 (sometimes cuad)
penta=5
hexa=6
hepta=7 (sometimes septa)
octa=8
nona=9... and the list continues
3) Lastly, just write out the formula with the more electronegative element or polyatomic ion first(if you have the name the more electronegative one will be the element listed first) and using subscript(s), indicate the number of each part
The first step in writing a chemical formula is to identify the elements that are present in the structure. Then count how many of each are present. Write this number as a subscript following each element symbol.
There a few ways of writing chemical formulas.
This is a symbol chemical formula:
Mg + FeSO4 => MgSO4 + Fe
This is a worded formula:
Magnesium + Iron Sulphate => Magnesium Sulphate + Iron
The other formula is when you draw atoms with their symbol written in them.
Hope this helps,
If the symbol is one letter, it is capitalized. If the symbol is two letters, the first letter is capitalized and the second letter is lowercase. For example, the symbol for hydrogen is H and the symbol for calcium is Ca.
First, study the Periodic Table of Elements to learn the symbols of the elements. After that, it's pretty self-explanatory.
First letter capitalized, second letter (if there is one) lowercase.
Yes, a chemical formula is a way of representing the composition of a compound using chemical symbols and subscripts. It shows the types and number of atoms present in the compound. For example, the chemical formula of water is H2O, indicating that it is composed of two hydrogen (H) atoms and one oxygen (O) atom.
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
Chemical symbol is code for a chemical element. Chemical formula is way of expressing information.
H2S is the chemical formula of hydrogen sulfide. The ion sulfite has the chemical formula SO2-3. The hydrogen sulfite ion has the chemical formula HSO-3.
Rocks are mixtures and so do not have chemical formulas. Igneous rocks vary in composition, so there is no way of giving a formula.
A chemical formula... for those who don't already know...
I suppose that you think to a chemical formula. Example: table salt (sodium chloride) has the chemical formula NaCl.

For correction purposes the correct way to write this is H2O and it is the chemical formula for water.
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
Writing out a chemical equation for a specific chemical reaction.
draw a structural formula for organics, write a chemical formula (molecular formula or ionic formula) for simpler compounds.
