## What is the atomic mass of copper?

63.546 uCopper / Atomic mass

What is the atomic weight of an electron?

The invariant mass of an electron is approximately 9.109×10−31 kilograms, or 5.489×10−4 atomic mass units.

### What is the number of electron of copper?

29 electrons
The copper atom, shown above, has 29 protons in its nucleus and 29 electrons orbiting its nucleus.

Does copper have 34 or 35 neutrons?

Copper has an atomic number of 29 and a mass number of 63. The atomic number is the number of protons in the nucleus, and the mass number is the number of protons and neutrons in the nucleus. This means that the copper atom has 29 protons and 34 neutrons in its nucleus (29 + 34 = 63).

How do I calculate mass of copper?

If you’re trying to find the molar mass of an element, then you’ll take the average atomic mass listed in the periodic table. If you’re looking at the element of copper you would look in the periodic table and find that it has an average atomic mass of 63.55 AMU, so that’s the molar mass.

### How do you find atomic weight?

The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668. Carbon-13: 0.0111 x 13.0034 = 0.1443.

How can we find the atomic weight?

In an element atomic mass of an atom can be calculated by adding the mass of protons and neutrons.
