i mean when we have H2O ( we all know that h has +1 valence electrons and 0 has -2) back to my point H20 is produced by cross multiplying the valence electrons so it becomes H2O1 and therefore writting it as h20

From what I've learned, you cross the charges so that you can find out how many atoms of a particular element it would take to cancel out the charge of the other element so that the charge of the compound is zero.
For example: water. H20. the charge of H is 1 and O is -2, so it'd take 2 hydrogen atoms to cancel out the charge of O.

Because everybody who speaks Chemistry-speak, knows all these charges and do not need to be told. Think about it. It is unnecessary redundant information and a waste of the other persons reading time.

I don´t. never heard anybody who does it.
how do u cross a charge and what do u cross it with???

I usually circle them, not cross them.
