The semi empirical binding energy formula predicts the binding energies of neon-20, iron- 56, and uranium-238 within about 1\%. Make a table whose rows are the three isotopes, whose first four columns are numerical values of the four tennis in the formula, whose next four columns are each of these terms divided byA, and whose final column is the sum of the preceding four. Discuss in some detail what the table reveals.
Given initially 40mg of radium-226 (one of the decay products of uranium-238), determine,
(a) The amount that will be left after 500years.
(b) The number of 伪 particles the radium will have emitted during this time, and
(c) The amount of kinetic energy that will have been released.
(d) Find the decay rate of the radium at the end of the 500 year.
Using the semiempirical binding energy formula estimate the mass of a europium- atom.
