Based on the current information, it is impossible to definitively determine the specific metal that must be present in the unknown substance. Every option listed (Calcium, Lithium, Sodium, Potassium, Copper) provided is classified as a type of metal.
Explanation
## Step 1:Let's first examine the options that we have before us. For each element mentioned (Calcium, Lithium, Sodium, Potassium, and Copper), we look up its classification in the periodic table of elements.## Step 2: Browsing through their classifications, we find -- Calcium (Ca) is an alkaline earth metal.- Lithium (Li) is an alkali metal.- Sodium (Na) is also an alkali metal.- Potassium (K) again is an alkali metal.- Copper (Cu) is a transition metal.## Step 3:By the looks of it, all these elements are actually metals. As the question does not provide additional criteria to narrow it down further, based on the information we have currently, the unknown substance could contain any of the five options listed.Therefore, unless additional information is provided upon which we are able to make further discrimination, it is difficult to definitively "name the metal that must be present" with the data at hand at this point in the problem.
