How many unpaired electrons would you expect for chromium in Cr h2o 6 3 +? Is this a paramagnetic or diamagnetic material?

Because cr has +3 oxidation stateandH2O is a weak field ligand so it will notcausepairing of electrons and will have 3unpairedelectrons so it is paramagnetic whereas fe has+2oxidation state and CN is a strong field ligand so itwillcause pairing of electrons and 3 pairswill bethere so it is diamagnetic.

What is Valency of chromium?

Valency is the combining capacity of anelement.In the case of a metal, its valency is also equal tothenumber of chlorine atoms with which its one atom combines toformits normal chloride. Chromium forms two normal chlorideinthe oxidation states +2 and +3, and their chemical formulaareCrCl2 and CrCl3.

What is the Valency of magnesium?

Atomic number of magnesium is 12 andit'selectronic configuration is 2,8,2. Valency is numberofelectrons gain or loss to achieve noble gas configurationI.e.fully filled octet. Since magnesium has 2 electrons init'soutermost shell, hence it's valency is 2I.e.

What is the Valency of titanium?

Counting along a row from the left gives the numberofvalence electrons. Titanium is 4 elements fromtheleft and has 4 valence electrons. It is in arowcorresponding to n=4 so its electronic configuration as aneutralatom is [Ar]4s24d2.

What type of bond is chromium?

First discovered in 2005, Chromium,Molybdenum,Tungsten, and Rhenium, all have a special ability toform aquintuple bond; also known as a five foldbond. InChromium cases, di-chromium wasdiscovered to have aquintuple bond, which means that 10electrons areparticipating in the bond with metal -metal.

Are 3d electrons Valence?

The outer energy level for this atom is n = 4, anditcontains three electrons. You must recognize thateventhough the 3d sub-level is mixed in among the 4s and4psub-levels, 3d is not in the outer energy level, sotheelectrons in the 3d sub-level are notvalenceelectrons.

What do unpaired electrons do?

In chemistry, an unpaired electron isanelectron that occupies an orbital of an atom singly,ratherthan as part of an electron pair. The lessdirectional, morediffuse d and f orbitals, in which unpairedelectronsreside, overlap less effectively, form weaker bondsand thusdimerisation is generally disfavoured.

Why is chromium an electron configuration?

In writing the electron configurationforChromium the first two electrons will go in the1sorbital. After the 4s is full we put the remainingfourelectrons in the 3d orbital and end with 3d4. Thereforetheexpected electron configuration for Chromium willbe1s22s22p63s23p44s23d9.

Why is 3d written before 4s?

According to the Aufbau principle, the 4ssublevelis filled before the 3d sublevel because the4sis lower in energy. As the 3d sublevel becomespopulated withelectrons, the relative energies of the 4sand 3dfluctuate relative to one another and the 4sends up higherin energy as the 3d sublevelfills.
