Textbook Problem

(a) Write the complete a decay equation for 226Ra. (b) Find the energy released in the decay.

To determine

(a)

The α decay equation of 226Ra

Explanation

Given:

  226Ra

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

Where A is atomic mass number

The atomic mass of R88226a138 is 226 and

  A = 226 Z = 88

To determine

(b)

Energy emitted in the decay
