Probable you think to Cu(I) and Cu(II) but these are not different elements.
Two: copper and oxygen.
Copper is an element itself.
There are two atoms of Bromine (Br) and one atom of Copper (Cu) in this compound. Thus, there are two elements, but three atoms.
It is called a compound because it is composed of more than one single element. Copper oxide is compose of the two elements copper and oxygen.Because it is composed of two elements, copper and oxygen.
No - copper and iron are two separate elements. One does not contain any of the other.
Definitely a compound, because it contains two elements viz. copper and chlorine. NB When any two ( or more ) elements combine it becomes a compound.
No. Copper and oxygen are two separate elements.
Copper is a pure element it is not composed of any two other elements however it has many alloys such as Bronze, which is composed of Copper and Tin.

Iron and copper, steel and bronze are not elements.
Two elements in copper bromide (misspelled, not bromiNe)There is Cu (cuprum) and Br(bromium) in it.
(Cu4O2) contain two elements: copper and oxygen.
copper and oxygen
Many alloys contain two elements, for example Brass is copper + zinc, Bronze is copper + tin.
