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.β − decay of 3H (tritium), a manufactured isotope of hydrogen used in some digital watch displays, and manufactured primarily for use in hydrogen bombs.

To determine

β  Decay equation of 3H

Explanation

Formula Used:

A = N + Z

Where A is atomic mass number

Z = Number of protons in a nucleus

X = symbol for the element

In the expression below:

XZAN

Z = Number of protons in a nucleus

X = symbol for the element

We know that

A = N + Z

Where A is atomic mass number

The atomic mass of H132is 3 and

A=3Z=1N=2

Thus after Beta decay, an electron and an antineutrino releases

Thus,
