In the following eight problems, write the complete decay equation for the given nuclide in the complete X Z A N notation. Refer to the periodic table for values of Z.α decay of 210Po, the isotope of polonium in the decay series of 238U that was discovered by the Curries. A favorite isotope in physics labs, since it has a short half−life and decays to a stable nuclide.

To determine

αdecay equation of 210Po

Explanation

Formula Used:

A = N + Z

Where A is atomic mass number

Z = Number of protons in a nucleus

In the expression below:

XZAN

Z = Number of protons in a nucleus

X = symbol for the element

We know that

A = N + Z

WhereAis atomic mass number

The atomic mass ofP84210o126is 210 and

A = 210 Z = 84N = 126
