Question

. Write the following isotope in nuclide notation (e.g., “ ”): copper-70

Answer 1

Answer:

${\boxed{\text{ _{29}^{70} {Cu}}}$

Explanation:

The atomic number (Z) of copper is 29 and this isotope has an atomic mass (A) of 70.

The general symbol for an isotope E is $_{Z}^{A}\text{E}$.

The atomic number is a left subscript, and the atomic mass is a left superscript.

$\rm {\text{The nuclide notation for copper-70 is }}{\boxed{\textbf{ _{29}^{70} {Cu}}}$
