The molecule XZ2 is formed from the hypothetical elements Z and X.  In that molecule both of the Z atoms are bonded to the X atom (and not to each other). The X-X distance in X2 is 0.136 nm and the Z-Z distance in the Z2 is 0.143 nm.  What is the predicted bond length for the X-Z bond in the molecule XZ2?
