What is the proper way of writing the chemical formula?

Answer 1

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

Answer 2

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.

Answer 3

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,

Answer 4

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.

Answer 5

The proper way of writing a chemical formula is to represent the elements present and their respective proportions in the compound using symbols and subscripts. The elements are typically listed in order of increasing atomic number.

Answer 6

First, study the Periodic Table of Elements to learn the symbols of the elements. After that, it's pretty self-explanatory.

Answer 7

First letter capitalized, second letter (if there is one) lowercase.
