Question

indicate the number of protons, neutrons, and electrons in $_{29}^{65}cu$.
part 1 of 3
how many protons are in the above isotope?
part 2 of 3
how many neutrons are in the above isotope?
part 3 of 3
how many electrons are in the above isotope?

Explanation:

Step1: Identify proton number

The atomic number (sub - script) gives proton number. For $_{29}^{65}Cu$, the atomic number is 29, so the number of protons is 29.

Step2: Calculate neutron number

The mass number (super - script) is the sum of protons and neutrons. Mass number = 65, protons = 29. Neutrons=Mass number - Protons. So, neutrons = 65 - 29=36.

Step3: Determine electron number

In a neutral atom, the number of electrons is equal to the number of protons. Since this is a neutral isotope of copper, electrons = 29.

Answer:

Part 1 of 3: 29
Part 2 of 3: 36
Part 3 of 3: 29
