Why is the electron configuration for copper 1s22s22p63s23p63d104s1 instead of 1s22s22p63s23p63d94s2?
a filled sublevel is more stable than a half-filled sublevel.
the arrangement of electrons with the same spin is as small as possible.
the 4s orbital has higher energy than the 3d orbital.
electrons occupy orbitals of the highest energy levels first.

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) â 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
