(a)
Interpretation:
The
Concept Introduction:
Alpha decay reaction:
An alpha particle is a high energy particle that contains two protons and two neutrons. An alpha particle is symbolized by the Greek letter alpha or the element symbol for helium has
(b)
Interpretation:
The nuclear reaction equation for decay of Sodium-25 by beta emission has to be given.
Concept Introduction:
Beta emission reaction:
Beta particles are electrons (electrons with negative electric charge). Beta decay occurs when in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.
(c)
Interpretation:
The nuclear reaction equation for decay of Xenon-118 by positron emission has to be given.
Concept Introduction:
Positron emission reaction:
Positron particles are electrons with positive electric charge. Positron decay occurs when in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.
(d)
Interpretation:
The nuclear reaction equation for decay of Curium-243 by an alpha emission has to be given.
Concept Introduction:
Refer to part (a).
