The atomic number of Copper is 29, and the atomic mass is 63.546. What do these numbers mean in regards to protons, electrons, and neutrons?

Determine the prtons, electrons and neutons

Explanation:

The atomic number is the number of protons/electrons in an element. The atomic mass it the protons + the neutrons. So an atomic mass of 63.546 would round UP to 64. So, 64 - 29 = 35

Protons: 29

Electrons: 29

Neutrons: 35.

Because it has more neutrons than protons, it's an unstable element.
