In Universe , recently discovered by an intrepid team of chemists who also happen to have studied interdimensional travel, quantum mechanics works just as it does in our universe, except that there are eight orbitals instead of the usual number we observe here. Use these facts to write the ground-state electron configurations of the seventh and eighth elements in the first transition series in Universe . Note: you may use to stand for the electron configuration of the noble gas at the end of the row before the first transition series. seventh transition metal:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

: )

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
