Write the valence molecular orbital configuration of Ne2+. The fill order for Ne is as follows: ?2s ?*2s ?2p ?2p ?*2p ?*2p What is the bond order of Ne2+ according to molecular orbital theory?

Which statement for NH3 and NF3 is false? Electronegativities: N = 3.0, H = 2.1, F = 4.0. The bond angles in NF3 are smaller than those in NH3. Both are sp3 hybridized at nitrogen. The bond dipoles of NF3 are directed toward fluorine, whereas those in NH3 are directed toward nitrogen. The bond dipoles in NF3 are directed toward the more electronegative fluorine atoms. Both molecules have one unshared pair of electrons in the outer shell of nitrogen. The nitrogen atom can be described as utilizing sp3 hybrid orbitals in the nitrogen trifluoride molecule. The bond dipoles in NF3 oppose the effect of the unshared pair of electrons. The NF3 molecule is more polar than the NH3 molecule.
