Under what conditions will a gas be least likely to exhibit the ideal gas properties predicted by the ideal gas law?

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

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.
