A cobalt target is bombarded with electrons and the wavelength of its characteristic spectrum are measured. A second fainter, characteristic spectrum is also found because of an impurity in the target. The wavelength of the Kα lines are 178.9 pm (cobalt) & 143.5 pm (impurity). If atomic number of impurity is 5x, then value of x is___

Answer» A cobalt target is bombarded with electrons and the wavelength of its characteristic spectrum are measured. A second fainter, characteristic spectrum is also found because of an impurity in the target. The wavelength of the $K_{α}$ lines are 178.9 pm (cobalt) & 143.5 pm (impurity). If atomic number of impurity is 5x, then value of x is___
