Question

Electron capture decay equation of ¹⁰⁶In

Short answer

The β^- Decay equation of¹⁰⁶In is \(_{49}^{106}I{n_{57}} + {e^ - } \to _{48}^{106}C{d_{58}} + {\nu _e}\).

Step-by-step solution

What is atomic mass number ?

The amount of matter contained in an atom of an element is called its atomic mass.

Formula to be used

A = N + Z

Where A is atomic mass number

Z is the number of protons in a nucleus

X is the symbol for the element

In the expression below:

\(_Z^A{X_N}\)

Z is the number of protons in a nucleus

X is the symbol for the element

To determine the Electron capture decay equation of 106In

We know that

A = N + Z

Where A is atomic mass number

The atomic mass of \(_{49}^{106}I{n_{57}}\) is 106 and

A = 106 Z = 49 N = 57

Thus,

A = 106 N = 57 - ( - 1) = 58 Z = A - N = 106 - 58 = 48

Therefore, electron capture Decay equation of ¹⁰⁶In is \(_{49}^{106}I{n_{57}} + {e^ - } \to _{48}^{106}C{d_{58}} + {\nu _e}\).
