- In an ammonium, nitrogen has a valence of 4, and zero nonbonding electrons. What is the correct formal charge of nitrogen with 4 covalent bonds?A oxygen with one single bond and three lone pairs is a neutral oxygen an oxonium ion with formal charge -1 an oxyanion ion with formal charge -1 an oxyanion with formal charge +1 an oxonium ion with formal charge +1The 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 ofDraw all the resonance structures for periodate ion.Which of the following has a formal charge of +1 The bromine of HBr two of these The oxygen of hydroxide ion The nitrogen of ammonium ion The oxygen of hydroxonium ion
- Experimentally, the shape around the highlighted nitrogens is found to be trigonal planar rather than trigonal pyramidal predicted by the Lewis structure above. Sketch a resonance structure that would account for trigonal planar geometry about the highlighted nitrogens in uracil. Add formal charges to the four atoms that have non-zero formal charges.
