The number of elements in a compound depends on the compound in question. For example, water is a compound, H2O and it contains TWO different elements; hydrogen (H) and oxygen (O). Another compound would be ammonium hydroxide, NH4OH and it contains THREE different elements; nitrogen (N), hydrogen (H), and oxygen (O).
At least two. Theoretically, there is no upper limit.

an element is a single substance while a compound is made up of multiple elements. Theirs no way to now how many elements form to make a compound... only through a microscope/
Two: lead and iodine.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
A compound is composed of two or more elements. A compound of only two elements is a binary compound.
The chemical name of the compound is often based on the names of the elements that are part of it. However, for many simple organic compounds it is not possible to determine the component elements.
there are two elements: nitrogen (N) and hydrogen (H)
