copper has 2 stable isotopes
29
Copper has natural isotopes of 63,67. And other isotopes are known at least from 58 through 70. But these are unstable.
stableAnswer:Like many elements copper has many isotopes. Two of these are stable (63Cu and 65Cu) others are radioactive. The isotope with the longest half life is 67Cu with a half-life of almost 62 hours.
Both chlorine and copper have multiple isotopes, meaning they have different varieties of the element with varying numbers of neutrons in the nucleus. These isotopes of chlorine or copper have different atomic masses, but they share the same number of protons, which is what defines them as the element chlorine or copper.
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 is a metallic element. It is located in the d-block of the periodic table. Its relative atomic mass is 63.5 (relative abundance of two isotopes 63 and 65).
