Why are the transition metals so different in chemical character from the s block elements?

They have the ability to form at least one ion with a partially filled 3D orbital, this leads them to be able to switch between states of oxidation and act as catalysts for reaction . In solid form acting as a heterogeneous catalyst they have the ability to donate or accept electron pairs, weakening bonds in reactants lowering activation energy.
e.g. electron configuration of Ni 2+

Why Mn2 plus ion show maximum paramagnetic character amongst the bivalent ions of first transition series?
Manganese is a chemical element, designated by the symbol Mn. It has the atomic number 25.Paramagnetism in the transition elements is caused by the presence of unpaired electrons in the d sub-orbital, and results in these elements being attracted by a magnetic field.Thats why mn show maxium paramagnetic character among ions of first transition elements.
What are the elements in group 3-12 on the periodic tables called?
These chemical elements are called transition metals.
Why are f-block elements called inner-transition elements?
inner transition elements are those who have their last 3 shells incompletely filled. The f block elements have their last 3 shells incompletly filled . That is why they are also called as inner transition elements. what different between inner transition and outer transition elements
Are most elements metals nonmetals or matalloids?
The most of the chemical elements are metals. Most are transition metals (located in the middle of the Periodic Table).
Blank is the most important of the transition elements?
Blank is not a name for a chemical element.
What is praseoydmuim?
A chemical element, one of the inner transition elements.
What are the elements in Groups 3-12 called?
These chemical elements are called transition metals.

Which d block elements are not classified as transition elements?
Sc and Zn are not classified as transition metals. They does not have stable different oxidation numbers.
Is the inner electrons involved in chemical changes?
In case of non-transition elements they are not but in case of Transition elements the 2nd last (in d-block) and 3rd last (in f-block) shell also become involved in chemical bonding.
What is the modern periodic law of the?
The chemical properties of chemical elements have a regular character.
How many different chemical elements are there?
Now are known 118 chemical elements.
What is statement of the modern periodic law?
The chemical properties of chemical elements have a regular character.
