Copper is a metal element. Mass number of it is 64.
The element with mass number 64 is Gadolinium (Gd), which has 64 protons and neutrons in its nucleus. It is a rare earth element commonly used in various applications, including magnetic resonance imaging (MRI) contrast agents.
The element with a mass number of 64 and 35 neutrons is Bromine (Br). Bromine has an atomic number of 35, which determines its chemical properties, while the mass number is the sum of protons and neutrons in an atom's nucleus.
A = mass number z = atomic number so this one is a Ni isotope with a mass of 64
