For transition metals, like fe, not all of the valence electrons have to be used to form chemical bonds with other elements. Most transition metals have 2 valence electrons.

Group 2 (ii) (alkaline earth metals) 2:
Transition metal valence electrons. A valence electron can either absorb or release energy in the form of a photon. Some characteristic transition metal ions in turn can form brightly colored solutions. The number of valence electrons.
As for the electron configuration for transition metals that are charged (i.e. This tendency is called the octet rule, because each bonded atom has 8 valence electrons including shared electrons. Similarly, a transition metal tends to react to form a d 10 s 2 p 6 electron configuration.
A valence electron can exist in the inner shell of a transition metal. For fe this means we have 8 valence electrons. Periodic table group valence electrons;
These metals have a long way to go to get to eighteen electrons, and sometimes they cannot fit that many ligands in. Occasionally, electron counts can be as low as eight electrons. In the ground state, the electron configuration of the transition metals follows the format, ns 2 nd x.
Let's consider the chemistry of cobalt which forms complexes that contain either co 2+ or co 3+ ions. Perhaps this is where you are getting the idea of two valence electrons. Group 1 (i) (alkali metals) 1:
A large range of complex ions in various oxidation states, coloured complexes, and catalytic properties either as the element or as ions (or both). Most transition metals have an electron configuration that is ns2 (n−1)d , so those ns2 electrons are the valence electrons. Perhaps this is where you are getting the idea of two valence electrons.
Valence electrons are the sum total of all the electrons in the highest energy level (principal quantum number n). The transition metals have at least two valence electrons, and more. Can you tell how many valence electrons are in transition metals?
Transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one. Transition metals possess several interesting properties such as they can form ions with different charges. The transition metals have at least two valence electrons, and more.
These cases often occur in early transition metals, such as titanium or tantalum. Valence electrons also determine the electrical conductivity of an element. An atom consisting of a closed shell of valence electrons will usually be chemically inert.
No logic here, only tradition. But for most of the transition and inner transition elements, the valence electrons are the electrons present in the shells outside the noble gas core.
