Iron (Fe), 26 electrons in neutral atom, 23 in Fe3+. Rust, Fe203 has Fe3+ ions.
I believe it is Zinc

zinc (Zn)
Just zinc. Chemical symbol Zn, atomic number 30 and the first of the elements in group 12 of the periodic table.
Yes, elements from atom number 21 (Sc) to 30 (Zn) are the so called '3d-block'transition-elements, group 3 to 12 in period IV of the periodic table.
A substance that allows electrons to pass through easily is a transition metal. Transition metals organize forming a sea of delocalized electrons and metal cations, allowing electrons to pass through easily.
platinum is a metal because it is shiny but it can be a metalloid or transition metal
Metals behave in a rather unique way as far as their electrons are concerned.The electrons in metals are de-localised, which in effect means they are not bound to a particular atom, like a "sea of electrons".This property makes them good conductors of electricity because charged electrons can easily travel from one end of the metal to the other whilst maintaining that charge.

Zinc has 30 electrons.
ZINC, of course
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
Co
I don't think there is one.
The actinide series
How to determine these ions:metal cations: find the positive charge, and make sure it is qual to the group numbernonmetal anions: subtract 8 from the group numbertransition metals cations: the number of electrons lost
transition metal complexes shows the coloring property due to d-d transition of electrons presnt in d orbital. this transition occurs due to absorbnce of light energy.
Nickel is a metal and has 28 electrons when not ionized.
