The neutral atom copper-64 has 29 protons, and 35 neutrons and 29 number of electrons.
The number of electrons, protons, and neutrons of an atom is known from the atomic notation. Atomic notation represents showing the atomic symbol, atomic number, and atomic mass. In some periodic tables of elements, the position of the mass number and atomic number can be written differently, but generally the mass number is written at the top and the atomic number is written at the bottom before the atomic symbol.
The mass number is the number of protons to the number of neutrons. The atomic number indicates the number of protons and the number of protons in a neutral atom equals the number of electrons.
The atom has the atomic symbol Cu (copper) with atomic number 29 and mass number 64. So, it can be concluded that Cu has 29 protons. The number of electrons is the same as the number of protons, namely 29. Meanwhile, the number of neutrons:
Mass number = number of protons + number of neutrons
64 = 29 + number of neutrons
Number of neutrons = 35
So, the number of electrons, protons, and neutrons in the atom is 29, 29, 35.
