Answer:
B 29 protons, 27 electrons
Explanation:
The given specie is copper ion:
Cu²⁺
We are to find the number of protons and electrons it contains.
The number of protons is the positively charged particles in the atom.
Electrons are the negatively charged particles in the atom.
The number of protons is the same as the atomic number
Atomic number of copper = 29
Number of protons = 29
Now;
Charge = Number of protons - Number of electrons
2 = 29 - number of electrons
-27 = - number of electrons
Number of electrons = 27
