26 protons
All the isotopes of bromine have 35 protons.
Copper has natural isotopes of 63,67. And other isotopes are known at least from 58 through 70. But these are unstable.
All isotopes of carbon have 6 protons.
The element that has half as many protons as zinc would be copper. Zinc has 30 protons, while copper has 29 protons. This means that copper has one less proton than zinc, making it the element with half as many protons.
Copper isotopes are not always whole numbers because the atomic mass of an isotope is determined by the total number of protons and neutrons in its nucleus, which can vary. Copper has two stable isotopes, copper-63 and copper-65, with atomic masses that reflect the different neutron counts. The atomic mass of naturally occurring copper is a weighted average of these isotopes, leading to a non-integer value (approximately 63.55). This average accounts for the relative abundance of each isotope in nature.

Bronze is an alloy typically made of copper and tin. Copper has 29 protons and tin has 50 protons. The number of neutrons can vary based on the isotopes of each element present in the alloy.
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 2 stable isotopes
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.
The defining characteristic of an element is the number of protons in the nucleus. Copper always has 29 protons. It may have different numbers of neutrons, as in the common isotopes copper-63 and copper-65 which have 34 and 36 neutrons respectively.
An atom of copper has 29 protons.
All the isotopes of actinium has 89 protons.
All the isotopes of curium have 96 protons.
All the isotopes of actinium has 89 protons.
Copper's atomic number is 29. Thus, copper has 29 protons per atom. To be electrically neutral then, it must also have 29 electrons per atom.
All Carbon isotopes have 6 protons.
