Describe how you could show by adding aqueous sodium hydroxide and aqueous ammonia that a solution contained zinc ions. Result with sodium hydroxide
Excess sodium hydroxide
Result with aqueous ammonia
Excess aqueous ammonia

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.

sure im new too!

explanation:

you need to have a picture of the atom that way we can answer it
