What is the formal charge on the sulfur atom in so? use the periodic table as needed. express the formal charge numerically

Both the S and O belong to group 6A elements, thus, both possess similar valence electrons, that is, six and equivalent sharing of bonding electrons. The formal charge is determined by using the formula, formal charge = valence electrons - (nonbonding electrons + bonding electrons)

The formal charge on the sulfur atom in SO is:  

Formal charge on S atom = 6 - (4 + 2) = 0

Hence, the formal charge on the S atom is 0.  

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.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
