B. Example Calculations
1) What is the chemical formula for the compound Magnesium Sulfide?MgS because you take the two elements and use the element symbols to get the chemical formula
2) What is the name for the compound RaBr2?
Radium Bromide because you change the second element from INE to IDE
3) What is the chemical formula for the compound Copper(I) Fluoride?
CuF because of the charges of the two elements
4) What is the chemical formula for the compound Nitrogen Trichloride?
NCl3 because of the prefix tri which means 3
5) What is the Name for the compound NF3?
Nitrogen Trifluoride because of the 3 with the F
6) What is the chemical formula for this compound Iron(II) Sulfate?
FeSO4 because Fe is iron and SO4-2 is sulfate but since iron has (II) the two with iron and the negative 2 on sulfate cancel
