Explain the following variations in atomic or ionic radii, by completing the following sentences: fe > fe2+ > fe3+ 1. the 4s valence electrons in fe are on average from the nucleus than the 3d electrons, so fe is larger than fe2+. 2. because there are five 3d orbitals, in fe2+ at least must contain a pair of electrons. 3. removing one more electron from fe2+ to form fe3+ significantly repulsion, increasing the nuclear charge experienced by each of the other d electrons and decreasing the size of the ion.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
