Iron (Fe), 26 electrons in neutral atom, 23 in Fe3+. Rust, Fe203 has Fe3+ ions.
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

zinc :)
Zinc has 30 electrons.
The transition metal with 24 electrons is chromium (Cr) and its common ion with a +3 charge is Cr3+.
ZINC, of course
Thorium (Th) is an inner transition metal with 90 electrons. It is a radioactive element that belongs to the actinide series of the periodic table.
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.
Transition metals typically lose 1, 2, or 3 electrons to achieve a stable electron configuration. This helps them attain a full or half-full d subshell, which is more stable than an incomplete d subshell. The number of electrons lost by a transition metal depends on its position in the transition metal series and the specific chemical reaction.
Transition metals are the elements with atomic numbers: 21-30, 39-48, 55-80, 89-112.:
Nickel has 28 electrons when it is neutral, however the Iron(II) ion has 28 electrons as well.
The number of unpaired electrons in a transition metal ion is directly related to its hardness. Transition metals with more unpaired electrons tend to be harder because the unpaired electrons can participate in bonding interactions, making the metal more resistant to deformation. This is known as the relationship between hardness and the d-orbital occupancy of transition metals.
