How many protons electrons and neutrons does copper have?

Answer 1

Copper 63: 29 protons, 29 electrons, 34 neutrons

Copper 65: 29 protons, 29 electrons, 36 neutrons

Copper The number of protons in an atom of an element is the same as the atomic number. So finding the number of protons in an atom just consists of looking at a Periodic Table. Copper's atomic number is 29, so it has 29 protons.

In a neutral atom, the number of electrons will equal and balance the number of protons, so it would also be 29 electrons.

The number of neutrons will depend on the isotope you have. Atoms of the same element can exist with different numbers of neutrons - these are what we call isotopes. However, there are only two isotopes of copper, 63Cu and 65Cu, which have 34 and 36 neutrons respectively.

Answer 2

Copper's, or Cu's, atomic number is 29. Therefore, electrically neutral copper has 29 protons and 29 electrons. 63Cu and 65Cu are the two stable isotopes of copper. They have 34 and 36 neutrons in them, respectively.

Answer 3

Copper has 29 protons, 29 electrons, and either 35 or 36 neutrons depending on the isotope (most commonly 63Cu with 34 neutrons or 65Cu with 36 neutrons).

Answer 4

Copper has 29 protons in its nucleus.
Copper (Cu) always has 29 protons.

Answer 5

Copper has 29 protons, 34 or 36 neutrons (depending on which isotope) and 29 electrons.

Answer 6

29 protons, 29 electrons

The number of neutrons depends on the isotope of copper.

Cu-63 has 34 neutrons and Cu-65 has 36 neutrons.

Answer 7

Cu2+ has 29 protons and around 35 neutrons.

Answer 8

Copper 63: 29 protons, 29 electrons, 34 neutrons

Copper 65: 29 protons, 29 electrons, 36 neutrons

Answer 9

Copper's atomic number is 29. Thus it has 29 positively charged protons. To obtain a net charge of 0, copper must also have 29 electrons.

Answer 10

Copper has 29 protons and electrons and 63 or 65 neutrons, depending on the isotope.
