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 is not a chemical compound. Its a chemical element.A chemical element is a substance made up of atoms of only one type. IE: Copper. Or hydrogen. Or Helium. Or Lithium... (there are ninety two naturally occurring elements, and several more man made ones)
False.
Tetra stands for four. So there are four chlorine atoms in a tetrachloride.

False.
Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
Chlorine is an element, not a compound. Moreover, its a diatomic molecule, that is, a molecule of chlorine contains two atoms of chlorine.
No. Copper carbonate is a compound. As a rule of thumb if a substance has a two-part name it is probably not an element unless one of those word refers to its state (i.e. solid, liquid, gas, vapor)
There are three atoms.One copper atom and two chlorine atoms.
Tetra stands for four. So there are four chlorine atoms in a tetrachloride.
Deca stands for 10. So there are ten chlorine atoms is decachloride.
