The concept of valence electrons does get a little fuzzy when you consider $d$ block elements since the energies of the $\ce{3d}$ and $\ce{4s}$ subshells are quite similar so I think its better to avoid it. In the case of chromium, an electron from the 4s orbital moves into a 3d orbital, allowing each of the five 3d orbitals to have one electron, making a half-filled set of orbitals. Predict the products of each of these reactions and write balanced complete ionic and net ionic equations for each. Silver, #"Ag"#, is located in period 5, group 11 of the periodic table, and has an atomic number equal to #47#.
