![]() For these elements, the weight value shown represents the mass number of the longest-lived isotope of the element. The elements marked with an asterisk (in the 2nd column) have no stable nuclides.Lanthanoids and Actinoids are numbered as 101 and 102 to separate them in sorting by group. Group: There are only 18 groups in the periodic table that constitute the columns of the table.Elemental compositions of crustal rocks differ between different localities ( see article). Earth crust composition average values are from a report by F.In a sorted list, these elements are shown before other elements that have boiling points >0☌. The density of elements with boiling points below 0☌ is given in g/l. ![]() Write Electronic Structure of Chromium.List of Periodic Table elements sorted by → Atomic number No. Show Electronic configuration of Chromium. On which block Chromium element is present? In chromium 2electron present in k shell, 8 electrons present in L shell,13 electron present in M shell and remaining 1electron present in N shellģ) Valency : chromium show generally 2, 3,4,5,6 valency In chromium atom maximum 6 electron is In outer shellĤ) Atomic radius : atomic radius of chromium is 166 pmġ) It is mainly use to make stainless steel.Ĥ) It act as a inhibitor of corrosion because it’s resist of corrosionĥ) It is use in medicine for treatment of depressionĦ) It is also use as a catalyst in chemical reactionħ) It is use to formation of dye and paintsĨ) It is use in body to blood sugar for controlling diabetes. In this isotope 24 proton, 24 electron and 26 neutron is present It is present 4.3 %ĥ2Cr : atomic weight of this isotope is 51.9 amu In this isotope 24 proton, 24 electron and 28 neutron is present It is present 83.7%ĥ3Cr : atomic weight of this isotope is 52.9 amu In this isotope 24 proton, 24 electron and 29 neutron is present It is present 9.5%ĥ4Cr: atomic weight of this isotope is 53.9 amu In this isotope 24 proton, 24 electron and 30 neutron is present It is present 2.3%Įlectronic configuration of chromium atom is : 1S 2 2S 2 2P 6 3S 2 3P 6 3d 5 4S 1Įlectronic configuration in concert of shell is 2,8,13,1 Meaning of this word is colourġ) Atomic symbol: chromium is denoted by the symbol Cr.Ģ) Atomic number : atomic number of chromium is 24 In chromium atom 24 electron and 24 proton is present.ģ) Atomic weight/ mass: : Atomic weight of chromium is 51.9 amu In chromium atom 24 proton and 28 neutron is present.Ĥ) Position : it is place in 4 th row ( period) and 6 th column ( group)Ħ) Colour : chromium show steel grey colourġ0) Boiling point : boiling point of chromium is 2671 0 Cġ1) Melting point : melting point of chromium is 19070 Cĥ0Cr : atomic weight of this isotope is 40.9 amu Vanadium word is originated from Greek word ‘ chroma ‘. it is use from ancient times Chromium show anti ferromagnetic properties.ĭiscovery : chromium is discovered in 1798 by French chemist Nicholas Louris Vauqualin 21 stnumber element found in earth crust by their mass contain. It is found from earth crust in the form of chromite. Yeast, wheat, kidney are rich in chromium. it show anti Corrosion nature hence add in manufacturing in steel. It show lustrous, hard, brittle properties. Atomic Mass, Number, Physical, Chemical properties, Electronic configuration, Valency, Chemical reaction, UsesĬhromium 4 th number transition metal.
