The characteristic X-rays for the lines of K_(a) series in element X and Y are 9.87 Å and 14.6 Å respectively .If Moseley's equation sqrt(v) = 4.9 xx 10^(7) (Z - 0.75) is followed: The atomic number of Y is

The atomic numbers of three elements X, Y and Z are 9, 11 and 17 respectively. Which of these two elements will show similar characteristics and why ?

The k_alpha X-rays of aluminium (Z = 13 ) and zinc ( Z = 30) have wavelengths 887 pm and 146 pm respectively. Use Moseley's law sqrt v = a(Z - b) to find the wavelength of the K_alpha X-ray of iron (Z = 26).

X-rays emitted from a copper target and a molybdenum target are found to contains a line of wavelength 22.85nm attributed to the K_(alpha) line of an impurity element. The K_(alpha) lines of a copper (Z=29) and molybdenum (Z=42) have wavelength 15.42nm and 7.12nm respectively. Using Moseley's law, gamma^(1//2)=a(Z-b) . Calculate the atomic number of the impurity element.

The characteristics of elements X, Y and Z with atomic numbers, respectively, 33, 53 and 83 are:

Three elements X,Y,Z are following Dobereiner's Triad rule. If the atomic weight of X and Y are 10 and 26 respectively, then atomic weight of Z will be:
