a)
Interpretation:
The balanced equation for the nuclear reaction has to be written.
Concept Introduction:
Alpha decay:
It is a type of radioactive decay in which an atomic nucleus emits an alpha particle, which is also known as helium nucleus.
An alpha particle is equal to the nucleus of a
Balanced nuclear reaction:
For a balanced
b)
Interpretation:
The pacemaker battery enclosed in a metal case before being inserted into the chest cavity has to be identified.
Concept Introduction:
Pacemaker Battery:
An external device which is made up of wires and leads and it is used to regulate heartbeat when it placed under the chest.
