The correct ratio of the atoms of the two elements in the sample of copper chloride compound would be 1:2.
<h3>Atoms of elements</h3>
Copper chloride has a chemical formula, 
.
Thus, an atom of copper, Cu, combines with 2 atoms of chlorine, Cl.
The 2 chlorine atoms are recipients of an electron each from the copper atom which happens to have 2 electrons in its outermost valence shell.
Therefore, the ratio of copper to chlorine atoms in the compound is 1:2.
