No, because it is not possible to have half an element. Every atom is an element of some kind and if you split it in half or any other fraction it will become another element. Sometimes formulas are written as if there are half atoms or molecules but this is only because one of them is the important part. The calcium carbonate cement is composed of is one common example. It is often written as CaCO3.1/2 H2O because it is the calcium carbonate which is the important part. It really should be 2CaCO3.H2O
