(a)
Interpretation:
The balanced and completed
Concept introduction:
- Beta decay is the emission of an electron and the simultaneous conversion of a neutron into a proton in the nucleus. So increase the
atomic number by one. - When the beta emission a neutron is converted to a proton and the atomic number increases.
Beta Decay: 146C→N147 + e0-1
(b)
Interpretation:
The balanced and completed nuclear equation for the given electron capture has to be written.
Concept introduction:
Electron capture is the capture of a surrounding electron by a proton in the nucleus. The process is accompanied by the emission of g rays and results in the conversion of a proton in the nucleus into a neutron.
Electron capture: 5727Co + 0-1e → 5726Fe + υ00
(c)
Interpretation:
The balanced and completed nuclear equation for the given Alpha emission has to be written.
Concept introduction:
- The nuclear disintegration process that emits alpha particles is called alpha decay. An example of a nucleus that undergoes alpha decay is 238U. The alpha decay of 238U
- Alpha Decay: 23892U → H42e + T23490h
(d)
Interpretation:
The balanced and completed nuclear equation for the given Positron emission has to be written.
Concept introduction:
Positron Decay:
- Positron emission is outgoing particle has positive charge and a proton is converted into a neutron. It decreases the atomic number.
- Positron Decay: 2312Mg → N2311 + e01
- In positron emission a proton is converted to a neutron and the atomic number decreases.
