RAWR Say hi to Natalie the Dinosaur :DDD -Imma eat you-
The transition elements are all metals. If we compare transition elements with a few of the most similar main group elements we will find that there are just a few characteristic differences. Perhaps the most familiar main group elements that are similar in their properties are magnesium, aluminium, and lead.
Most people trying to answer this question with a textbook-type approach will talk about electronic structures. Transition elements are those that fit into the Periodic Table where the d-shells are partly filled, or where they are first complete. They comprise groups 3 to 12 of the modern periodic table.
I think that what they question might really be asking is "how are they different"?
Transition metals are moderately reactive to quite unreactive metals. The most reactive would be similar to aluminium in reactivity; none would be as reactive as magnesium. Lead would fit quite neatly with the typical reactivity of a transition metals.
There are three properties that transition metals quite characteristically show:
(i) They make brightly coloured compounds, especially with their salts. Compounds of magnesium and aluminium rarely are, and any colour can usually be associated with the other (negative ion) part of the compound. But lead (not a transition element) does make a lot of straw-coloured compounds, while zinc (usually regarded as a transition element, although its 3d and 4s shells are full) makes very few coloured compounds.
(ii) They show variable valency, which most main group elements do not. Once again, lead makes compounds with valencies of both 2 and 4, while zinc typically has only compounds where it expresses valency 2.
(iii) They make a wide variety of "co-ordination complexes". Several main group elements do as well, including all three of the elements that we have set up for comparison. But many of the other main group metals do not.
Transition elements (groups 3-12 ) are alike because they are all metals.
They are in the middle of the table and all have d electrons. The firsts series is, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn.

They are all metal elements, specifically transition metals.
all transition elements are metals
they are all transition metals and belong to group 6
Transition elements occupy central block. They are present between group3 to12.
Osmium is, itself, a transition metal.

No. Most of the metals listed are not transition metals and most transition metals are not in the list.
Transition element
All of them are metals. Those are in the d block.
Transition elements occupy central block. They are present between group3 to12.
Osmium is, itself, a transition metal.
These three metals, iron cobalt, and nickel, are ferromagnetic.
One property of transition metals is that all elements and compounds in transition metals act as a catalyst ( speeds up chemical reactions. )xcool77
transition metals
They all are soft. They all have lowest melting point among all other transition metals. From: Kansagra Mihir
