Can someone please fill this out for N2-? In my mind ther are 11 electrons. Nitrogen has 5 valence electrons, so 5*2+1=11, but I keep asking about this and people are telling me that there are 15 electrons. Where is the 7*2+1=15 coming from? And this is the picture I have to use for this quetion. Everyone keeps drawing a different diagram to fit in the 15 electrons. I'm so confused about this. I believe the molecular electron configuration is: (σ2s)2(σ*2s)2(π2p)2(π2p)2(σ2p)2(π*2p)1 Correct? That is 11, so I'm not sure why I keep getting different answers about this. Can you please help? Thanks
Depending on the protein under study, the bond angle of a drug molecule can become critical to successfully deactivating a viral protein. For this reason, chemists are frequently concerned with the 3D shape of their molecules and their bond angles. The oxygen atom shown in the structure has a tetrahedral electronic geometry, meaning we would predict that it would have 109.5° bond angles. However, the actual structure, the bond angles are smaller than 109.5°. Explain why this compression occurs. Make sure to discuss what’s happening around/what groups are present around the oxygen atom.
