Aflorist prepares a solution of nitrogen-phosphorus fertilizer by dissolving 5.66 g of nh4no3 and 4.42 g of (nh4)3po4 in enough water to make 17.0 l solution. what is the molarity of nh4+ in the solution?

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

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.
