1.What is the formula for manganese (II) fluoride?
2. What is the correct name for the ionic compound K3PO4?
3. What is the correct name for the ionic compound Fe(NO2)2?
1. since mn is said to have 2+ charge in this case and f has 1- charge then its MN2+F- but the charges have to cancel out so we need to have 2+ and 2- charge so MN is 2+ but F- is only 1- so we need to add one more F- so formula is MNF2
