For the diatomic molecule F-Br the following values areknown:

Allen-Scale Electronegativities: F= 4.193, Br = 2.685
Bond length = 175.7 pm
Dipole moment = 1.73 D

Determine the difference in electronegativity (ΔX) for thesemolecules, and state if the
bond is ionic, polar, or covalent

How do you write Molecular Oribital Configurations?

The N2+ ion can be prepared by bombarding the N2 molecule withfast-moving electrons. Predict the following properties of N2+:a)electron configuration b)bond order c)magnetic properties d) bondlength realtive to the bond length of N2 (is it longer orshorter?).

Using the molecular orbital model to describe the bonding in F₂⁺, F₂, and F₂⁻, predict the bond orders and the relative bond lengths for these three species. How many unpaired electrons are present in each species?
