![]() ![]() Let us write down the electronic configuration (e.c.) of chromium in its ground state. After this you can identify the group and period using the principal quantum number and the orbital in which the last electron takes place. periodic table, in full periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic number i.e., the total number of protons in the atomic nucleus. Write Electronic Structure of Chromium.Hint: An attempt to solve this question can be by writing down the electronic configuration of the element. Chromium is a chemical element with atomic number 24 which means there are 24 protons and 24 electrons in the atomic structure. 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 Notice that aluminum borders the line, but it is considered to be a metal since all of its properties are like those of metals. Vanadium word is originated from Greek word ‘ chroma ‘. On the periodic table, the elements colored yellow, which generally border the stair-step line, are considered to be metalloids. 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. ![]() Subscribe to Envato Elements for unlimited Stock Video.
