Copper has natural isotopes of 63,67.
And other isotopes are known at least from 58 through 70. But these are unstable.
26 protons
If you are talking about stable isotopes then there are two, 63Cu and 65Cu.
Because copper has isotopes. All Copper atoms have exactly the same number of protons, but not all of them have the same number of neutrons. The ones with different numbers of neutrons are known as isotopes. A given sample of Copper will contain various amounts of each of its isotopes. The atomic mass (weight) is an average weight, based on the percentages of the isotopes
The isotopes of copper have the relative atomic masses of 63 and 65 and these are approximations. The exact values contain decimal figures.
Copper has the natural isotopes Cu-63 and Cu-65.

If you are talking about stable isotopes then there are two, 63Cu and 65Cu.
There are 29 isotopes of copper, with mass numbers ranging from 52 to 80. However, only two isotopes, copper-63 and copper-65, are stable. The most abundant isotope is copper-63, making up about 69% of naturally occurring copper.
Copper has two stable isotopes, copper-63 and copper-65. The relative percentage abundance of these isotopes is approximately 69.17% for copper-63 and 30.83% for copper-65.
The natural isotopes of copper are: Cu-63 and Cu-65.

Some do, some don't. Scandium and manganese, for example, do not, copper has only two isotopes.
