Complete the Lewis structures for diazine (C5H4N2) showing the two most common resonance forms. Draw the Lewis structures with the formal charges minimized.

See explanation and image attached

Explanation:

Lewis structures dot structures that show the number of valence electron in a molecule. Sometimes, we show bonded electrons using a single line as in the image attached.

Two images are shown. They are the both resonance structures of diazene. The both structures only differ in the arrangement of electrons as we can see from the image.

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.
