Question

use the following information to answer the next two questions
the highest concentrations of copper in the body are found in the liver and in the brain. copper plays a role in the formation of hemoglobin and phospholipids. organ meats, shellfish, grains and seeds are all good sources of copper.

the number of protons, neutrons and electrons that could be found in a copper atom is

a. 29 protons, 64 electrons, 29 neutrons
b. 29 protons, 64 electrons, 64 neutrons
c. 29 protons, 29 electrons, 35 neutrons
d. 29 protons, 27 electrons, 35 neutrons

select one:
a
b
c
d

Explanation:

Step1: Find copper's atomic number

Copper has an atomic number $Z=29$, so protons = 29. In neutral atoms, electrons = protons = 29.

Step2: Calculate neutrons for Cu-64

Copper's common isotope is $^{64}\text{Cu}$. Mass number $A=64$. Neutrons = $A-Z = 64-29=35$.

Step3: Match with options

Check which option has 29 protons, 29 electrons, 35 neutrons.

Answer:

C. 29 protons, 29 electrons, 35 neutrons
