This value is set proportional to the derivative o
This value is set proportional to the derivative of n with respect to r in Kato's theorem. Thisquantity is related to the square root of the frequency of an emitted K-alpha line by Moseley's Law.According to the semi-empirical mass formula, binding energy is greatest when this quantityapproximately equals twenty-six. A screening constant is subtracted from this value in order todetermine effective nuclear charge in Slater's rules. For hydrogen-like atoms, the (*) square of thisquantity appears in the numerator of the Rydberg formula. Fission occurs when this quantity is greater thanabout seventy. Mendeleev ordered elements by this parameter in the Periodic Table. For 10 points, namethis quantity symbolized Z, the number of protons an element has.
