Some examples are: Mn, Fe, Co, Ni, Cu. .
Fe and Co
Cu
copper (Cu)
2 Fe + 3 CuO -> Fe2O3 + 3 Cu
They belong to the d group. They make colourfull compounds or ions. Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn are few examples.

Fe, or Iron, element 26 belongs to group 8 on the periodic table, although since it is in the transition metals, you cannot rely solely on the group number to find how many valence electrons it has
Neither. Fe is the symbol for elemental iron on the Table of Elements.
