Scientists have developed a new drug known to cure a previously incurable disease. What best explains if the new drug is a compound or not?

All the drugs ever formed are compounds. An element in itself can't cure a disease, but couple with other elements, most probably also with carbon, it can attain attributes that may help in fighting diseases. Organic drugs are also manufactured by scientists by using animals and plant parts and replicating them. Compounds also make up non-living things. Salt (NaCl) is a classical example of this.

Explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
