A target element A is bombarded with electrons and the wavelengths of the characteristic spectrum are measured. A second characteristic spectrum is also obtained because of an impurity in the target. The wavelength of the Kα lines are 196 pm (element A) and 169 pm (impurity). If the atomic number of impurity is z=(10x−1). Find the value of x. (atomic number of element A is 27).
