Bragg's law (Sir W.L. Bragg; 1912)
While a beam of x-rays strikes at crystal surface wherein the layers of atoms or ions are separated regularly, the maximum intensity of the reflected ray takes place while the complement of the angle of incidence, theta, the wavelength of x-rays, lambda, and the distance among layers of atoms or ions, d, are associated by the equation
2 d sin theta = n lambda,
Where n is an integer.
Q. The radioactive isotope 84Pa214 undergoes a successive disintegration of two α decays and two β decays. Find the atomic number and the mass number of the resulting isotope.
No;(Personal Note:Please Rate this and let me know if this helps) Reason: From the quantisation of charge charactersistic, we can say that charge comes in integral multiple of e (
