Determine the number of protons in all isotopes of Cu.

Understanding isotopes

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons. This means that all isotopes of an element have the same atomic number.

Identifying the atomic number of Cu

The atomic number of an element is equal to the number of protons in its nucleus. For copper (Cu), the atomic number is 29, which means all isotopes of copper have 29 protons.

\(\boxed{29}\)

The number of protons in all isotopes of Cu is \(\boxed{29}\).
