Pb10S10 The prefix deca in decasulfide means that there are 10 sulfide ions in the formula, each with a 2- charge. So the total negative charge is 10 x 2-, which equals 20-. To balance the total sulfide charge, you need enough lead II ions to equal 20+, so that means 10 lead II ions, which equals a charge of 20+. This is not really the correct way to name this compound. It should just simply be lead II sulfide, and the proper formula would be PbS, which, if you look at the ratio of lead to sulfide ions, which is 10:10, the formula for lead II decasulfide should be reduced to PbS.
Tetraphosphorus decasulfide.

what is formula for coil coating WFT formula
Yes, it is possible for an empirical formula to be the same as the molecular formula. For example, Lactic acid's molecular formula is C3H6O3, which would make its empirical formula CH2O.
