Concept explainers
(a)
Interpretation:
The balanced equation for the alpha decay of gold-173 should be determined.
Concept Introduction:
When a radioactive element decays it will have different types of emissions: alpha, beta, positron, gamma, etc.
This emission can be represented by equations. The addition of the mass number and
When the atomic number changes then the element will also be changed.
(b)
Interpretation:
The balanced equation for the beta decay of iodine-138 should be determined.
Concept Introduction:
When a radioactive element decays it will have different types of emissions: alpha, beta, positron, gamma, etc.
This emission can be represented by equations. The addition of the mass number and atomic number must be the same on both sides of the equation.
When the atomic number changes then the element will also be changed.
(c)
Interpretation:
The balanced equation for the capture of an electron by cadmium-104 should be determined.
Concept Introduction:
When a radioactive element decays it will have different types of emissions: alpha, beta, positron, gamma, etc.
This emission can be represented by equations. The addition of the mass number and atomic number must be the same on both sides of the equation.
When the atomic number changes then the element will also be changed.
