It's a transition where an electron jumps from one d orbital to another. Normally these are degenerate (the d orbitals have the same energy), but under some conditions, such as the presense of ligands, the degeneracy can be removed so that there is a specific energy (and therefore wavelength) associated with these transitions.
These sorts of transitions sometimes have energies located in the visible band, and it's one reason transition metal ions (and complex ions in particular) tend to be highly colored.
The elements having partially filled d or f orbitals are Transition elements while elements having partially or full filled d orbitals are d- block elements.
d block elements, transition metals, transition elements are synonyms.
The definition of d block after the IUPAC recommendation is "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete dsub-shell".
These elements have electrons in their "d" orbitals, according to Crystal Field Theory when such elements form the coordination compounds their"d" orbitals becomes split into two groups with respect to energy and TRANSITION of electrons takes place between these two groups which is also responsible for the appearance of colors in transition metal complexes.
the main blocks of element Cr in is d-block orbital in the periodic table because element Cr is a transition element.
No the p block of elements does not contain transition metals. The lowest energy level to allow d orbitals is not the fourth energy level.
The only similarity elements and compounds share are that they're the building blocks of matter. Their differences are that elements are are made of only one type of periodic element. Compounds are made of at least two periodic elements bonded together. For example, salt is a compound of sodium-chloride and the helium in balloons is made up entirely of helium molecules.
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
Mercury (Hg) is blue on the periodic table because mercury is liquid by itself at room temperature. The only other element on the periodic table that is liquid by itself at room temperature is bromine, but mercury is the only metal liquid at room temperature. This is also one reason why mercury is used in some thermometers.The above may be true of some versions if the periodic table, where the colour, according to the state of matter, under normal conditions. Some versions show all the transition metals as blue, mercury in group 12 is often considered to be a transition metal. The colours used to identify blocks or elements on periodic tables are not standardised around the world.
Group nine to eighteen (B-Families) of 'd' and 'f' blocks of periodic table are transition elements.
the main blocks of element Cr in is d-block orbital in the periodic table because element Cr is a transition element.

No. They are two different elements. They are not compounds, which are made up of elements Look at a periodic table. Those are your most basic building blocks as a beginner chemist.
D block elements are at the center of the periodic table; f block elements are at the bottom.
The individual blocks are the individual elements, ie: Hydrogen, Helium, Lithium etc etc.
This is so, because these rows separate f-block of the elements from other blocks.
There are total 18 groups in the periodic table that contains elements having same properties.
Direct quote from my textbook: "Elements are the chemical building blocks of matter."MATTER
Letters are the building blocks of words, and elements are the building blocks of all matter.
Transition metals form ions with incomplete d orbitals.
