which element is more electronegative than phosphorus but less electronegative than oxygen? arsenic silicon fluorine nitrogen
13. Element X is more electronegative and smaller than nitrogen. X has valence electrons in the second shell and forms ions with a charge of 1. Deduce the identity of X and state its name.
1. Why is the Electron Affinity of chlorine more favorable (that is, more negative) than fluorine? This is surprising as fluorine is the most electronegative element. 2. The second Electron Affinity for oxygen is positive and very large, meaning it is unfavorable. But the most common ion of oxygen is oxide, O2−. How can you explain this, aside from using the octet rule? 3. Ammonia (NH3) has a greater dipole moment than nitrogen trifluoride (NF3). This means that ammonia is...
Writing Lewis Structures d. Because oxygen is more electronegative than nitrogen, it is more likely to have a negative formal charge. Which structure would then be the best description of N,O? e. Are the structures that have the N-O-N bond skeleton resonance forms of the structures with the N-N-O skeleton? Explain. 4. Hydrogen isocyanide, HNC, will convert to hydrogen cyanide, HCN, over time. Use their Lewis structures to explain this.

Which element is more electronegative: F, O, N, Li?
Which of the following elements most likely has the same number of valence electrons as silicon (Si)? arsenic (As) O sulfur (s) O germanium (Ge) O phosphorus (P)
In a covalent bond between two atoms, the more electronegative atom will attract more electron density toward itself, producing a polar bond. The more electronegative element will carry a partial negative charge, whereas the less electronegative element will carry a partial positive charge. The direction of the bond dipole is always toward the more electronegative element. This is often indicated by an arrow, as shown in the figure. The magnitude of the bond polarity can be estimated by using the...
12. Why is the phosphorus cycle described as less complicated than the nitrogen cycle? 13. A lake in New York State is fed by a watershed consisting of a single river on its northern end. For many decades this watershed has been forested. However, recently all of the trees on the northern end of the lake were logged. The roots were also removed, and all that remains is bare soil. What effect will this logging have on the watershed's hydrology...
