Express your answer in condensed form in order of increasing orbital energy as a string without blank space between orbitals. for example, [he]2s22p2should be entered as [he]2s^22p^2.

There are 6 elements that are given and these are:Nickel, Selenium, Cadmium, Uranium, Lead, and Cesium. These are their condensed electronic configuration.
Ni – [Ar] 4s2 3d8Se – [Ar] 4s2 3d10 4p4Cd – [Kr] 5s2 4d10U – [Rn] 7s2 5f4Pb – [Xe] 6s2 4f14 5d10 6p2CS – [Xe] 6s1

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
