Question

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?

Answer 1

Answer:

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.
