Suppose there are two known compounds containing the generic elements X and compound. One sample contains 0.33 g of X and the other contains 0.42 g of X. Identify plausible sets of formulas for these two compounds

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.

if it's not useful, feel free to report for mistake in answer.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
