How many neutrons in copper 65?

Answer 1

Cu 65 has the same number of protons as any other copper, which is 29. It also has 29 electrons since the charge is neutral. The number 65 only changes the number of neutrons, which in this case would be 36.

Answer 2

Copper-65 has 34 neutrons. This can be calculated by subtracting the atomic number of copper (29) from its Atomic Mass (65).

Answer 3

Copper's atomic number is 29, therefore it has 29 protons in the nuclei of its atoms. In a neutral copper atom of any isotope, the number of electrons will also be 29.

Answer 4

Copper is element 29 and so 29 protons and thus 29 electrons to balance. 63-29 = 34 so there are 34 neutrons with Copper 63.

Answer 5

Cu2+ ion has 29 protons and 27 electrons

Answer 6

36
