Which atom carries a positive formal charge in the ammonium cation? ON H N and H None

The structure shown below is missing formal charges, but all electrons are shown. What is the formal charge on (A) the oxygen atom (B) the nitrogen atom and (C) the carbon atom that is double-bonded to the nitrogen ? N.

The oxygen atom in acetone possesses ____ unshared pairs and ____ shared pairs of electrons. The number of electrons that belong to oxygen is ____. Oxygen is a Group ____ element. The formal charge on oxygen in acetone is ____.

The carbon atom owns one electron from each of shared pairs and two electrons from unshared pair. The number of electrons that belong to carbon is . Carbon is a Group element. Since the carbon atom has one more electron than it would in the neutral, unbonded state, it has a formal charge of –1 . The Lewis structure for the methyl anion is The lithium fragment must have a formal charge of

Ethanol, , is a compound in which the formal charge on all the atoms is zero. Under certain conditions the bond can be broken so that both electrons remain with the oxygen atom. The products are In this structure the oxygen owns one electron from shared pair and two electrons from each of unshared pairs. The total number of electrons belonging to oxygen is Oxygen is a Group element. The formal charge on the oxygen atom is . The correct Lewis structure for the ethoxide ion is Note that the other fragment, the proton, leaves with a formal charge of +1.
