Most scientists simply regard the transition metals as the elements in the d-block (groups 3-12) on the periodic table. There are total of
38 elements
in this group including Cobalt, Nickel, Iron, Rhodium, Gold, Silver, Cooper, Scandium, Titanium, Vanadium, Manganese, Zinc and Mercury.
How many elements are in the transition metal group?
The transition metal group is called the “d-block” of the periodic table. There are
35 elements
located in the d-block.

What is the first transition series called?
The first transition series is called
__________transition series
.
What are transition elements and their characteristics?
Transition elements (also known as transition metals) are
elements that have partially filled d orbitals
. IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital.
Are the 14 transition metals?
Typically the elements of the post-transition metals include any metal in groups 13, 14, and 15 which are
aluminum
, gallium, indium, tin, thallium, lead, and bismuth.
Why is it called transition metals?
Because they are all metals
, the transition elements are often called the transition metals. As a group, they display typical metallic properties and are less reactive than the metals in Groups 1 and 2. Some of the more familiar ones are so unreactive that they can be found in nature in their free, or uncombined state.
Are transition metals shiny?
The transition elements share some physical properties with all metals: they conduct electricity in the solid and liquid states.
they are shiny when freshly cut
.
Is Potassium a transition metal?
At high pressure the alkali metals potassium, rubidium, and cesium transform to metals that have a d
1
electron configuration, becoming
transition metal-like
.
What are typical transition elements?
Transition elements are the one
which has the partially filled d orbitals
example Fe, CO, Ti etc., and non-typical transition elements are the one which has completely filled d orbital example Zn, Cd, Hg because they have completely filled inner or penultimate d-orbitals.
What are the inner transition elements?
The period 7 inner transition metals
What are transition elements write its four characteristics?
(i) All transition elements are metallic in nature, e.g., all are metals. (ii) These metals exhibit variable oxidation states. (iii) Transition metal atoms or ions generally form the complexes with neutral, negative and positive ligands. (iv)
Compounds of transition metals are usually coloured
.
How do you identify transition elements?
- have large charge/radius ratio;
- are hard and have high densities;
- have high melting and boiling points;
- form compounds which are often paramagnetic;
- show variable oxidation states;
- form coloured ions and compounds;
- form compounds with profound catalytic activity;
What are transition elements write 2 characteristics?
They
show variable oxidation states
. They exhibit catalytic properties. They generally form complex compounds. They generally form coloured compounds.
Are transition metals hard?
They have high melting and boiling points, and all are solids at room temperature, except for mercury (Hg), which is a liquid. Transition metals are
also high in density and very hard
. Most of them are white or silvery in color, and they are generally lustrous, or shiny.
