Write nuclear symbols for each of the isotopes Carbon-14 Cobalt-60 Gold-197 Uranium-235

Marina CMI [18]

Answer and explanation:

The nuclides with the same atomic number, but different mass numbers are isotopes.

So, in this case, each species will have the same atomic number and a different mass number, that will be the same that it is written in the name of the element:

$\begin{gathered} -\text{ Carbon-14:}C_6^{14} \\ \\ -\text{ Cobalt-60: }Co_{27}^{60} \\ \\ -\text{ Gold-197: }Au_{79}^{197} \\ \\ -\text{ Uranium-235: }U_{92}^{235} \end{gathered}$
