The first artificial transmutation of an atom was achieved by Rutherford in 1919 - Leaving Cert Physics - Question (i) - 2015

The nuclear equation for the transmutation of nitrogen-14 by an alpha particle can be written as:

$^{14}_{7}N + ^{4}_{2}He \rightarrow ^{17}_{8}O + ^{1}_{1}H$

In this equation:

• The nitrogen-14 nucleus (represented as $^{14}_{7}N$) interacts with an alpha particle (helium nucleus represented as $^{4}_{2}He$).
• This interaction results in the formation of an oxygen-17 isotope (represented as $^{17}_{8}O$) and a proton (represented as $^{1}_{1}H$).
