Group 1 metal iions have low tendencies to form complexes because their charge densities are low and they do not have empty orbitals of low energies. however they can form stable complexes with hard donor atoms such as polydentate ligand
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.
Scandium and zinc (and probably those below them in their groups, but I'm uncertain of that) are not considered to be transition metals, as they do not form ions with partially filled d-subshells.
Aluminium is not considered a transition metal because it does not have partially filled d-orbitals in its electronic configuration. Transition metals are defined by their ability to form stable ions with partially filled d-orbitals, whereas aluminium's electron configuration fills its 3p orbital, making it belong to the group of post-transition metals.
Early transition metals are does starting at the beginning of the transition metals (i.e. Sc) and going through about d5 which would be Mn. These metals are less electron rich as compared to the so-called "late" transition metals and the chemistry of each is somewhat different and definitely unique. Hardness and softness of the each of these groups changes (see Hard Soft Acid Base Theory) as does the stable oxidation states and coordination numbers.
Transition metals are d-block elements. Their general electronic configuration is (n-1)d1-9 ns0-2. The last electron enters the d-subshell.Inner Transition metals are f-block elements. Their general electronic configuration is (n-2)f1-13(n-1)d1-9 ns0-2. The last electron enters the f-subshell.
Yes, transition metals are known to be stable. This is because, both, their ions and compounds are also considered to be stable.
Technetium has no stable isotopes.
transition elements are not as reactive as alkali metals or alkaline earth metals.. this is so because of the valence electronic configurations. alkali metals have ns1 configurations which have easy chances of loosing electrons so as to gain the stable state. Attaining a stable state is the law of nature. hence to attain it they have to redily donate electron. this is not so easily possible for the transition elements..
Sc and Zn are not classified as transition metals. They does not have stable different oxidation numbers.
Zinc has the largest ionization energy among transition metals due to its high effective nuclear charge and stable electron configuration.
cations or positive ions, as transition metals lose electrons to achieve a stable arrangement
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.

Scandium and zinc (and probably those below them in their groups, but I'm uncertain of that) are not considered to be transition metals, as they do not form ions with partially filled d-subshells.
Transition metals typically lose 1 to 4 electrons to achieve a stable electron configuration. The number of electrons lost depends on the specific transition metal and its position in the periodic table.
''Cations'' breh. Transition metals often form ions wihout complete octets that's why all the stable ions are all cations You can also tell that they form cations because some of the trans metals form colored compounds and give off light. Light is only given off by cations, not anions.
Metals typically become cations by losing electrons to attain a stable electron configuration. Transition metals and main group metals are common examples of elements that form cations.
It is IMPOSSIBLE to form elements of any kind or group other than by nuclear processes. There is no special one for transition elements.
