Use molecular orbital theory to describe the bonding in the following. For each one, find the bond order and decide whether it is stable. Is the substance diamagnetic or (a) Be_2 bond order Is it stable? stable unstable Is it diamagnetic or paramagnetic? diamagnetic paramagnetic (b) Ne_2 bond order Is it stable? stable unstable Is it diamagnetic or paramagnetic? diamagnetic paramagnetic
