Construct a simple (i. e., no orbital hybridization, no electron promotion) valence bond wave function for the first bond in Li2. The wave function is a product of a coefficient and a function of two orbitals. The coefficient is labeled for the type of atomic orbital involved in the bond, and depends on the distance (R) between the two electrons in the bond. Assume the electron configuration of each atom before bonding is 1s22s12px02py02pz0.

i think it is true since you can test the answer and can use observations to complete it.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
