The defining characteristic of an element is the number of protons in the nucleus. Copper always has 29 protons. It may have different numbers of neutrons, as in the common isotopes copper-63 and copper-65 which have 34 and 36 neutrons respectively.

Why did John Dalton think that elements are made of single atoms?
The constant proportions - combining different substances into other substances always required the same proportions of each substances; in the case of gases, the numbers come in simple ratios. For example, 2 volume units of hydrogen + 1 volume unit of oxigen combine to form water.
A neutral atom has the same number of protons as it does neutrons?
no. an atom is made up of protons neutrons and electrons. protons have a charge of plus one electrons have a charge of minus one neutrons have no charge. therefore the number of protons and electrons must be equal (balancing the charges) for the atom to be neutral. ;)
How does the idea of atoms explain the priciple of conservation of matter?
The idea of atoms explains the conservation of matter. In chemical reactions, the number of atoms stays the same no matter how they are arranged. So, their total mass stays the same.
Why do all atoms have a different number of protons?
Dear questioner,As an answer to your question I should mention there are atoms which have the same number of protons but are considered different. These atoms are called Isotopes. Isotopes of an element have the same number of protons but the number of Neutrons are not the same. Isotopes have the same chemical virtues but in the physical virtues related to mass they are a bit different.
Isotopes are atoms that have the same number of protons but a different?
Isotopes are atoms of a given element that have the same number of protons but a different mass number and therefore a different number of neutrons.
In a sample of pure copper all atoms have the same what?
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
Is substance made of copper atoms and chlorine atoms combined together will have the same chemical properties as copper and chlorine individually true or false?
False.
Is copper an element which is made up of atoms?
Yes, everything is made up of atoms, but the atoms in copper are all the same kind, just copper atoms, so it is an element.
Why can gold and copper have the same extensive properties?
Extensive properties have to do with the amount or size of a substance. Gold and copper samples can be made to have the same mass or the same volume, or the same number of moles, or atoms.
What mass of copper contains the same number of atoms as 68.7 g of iron?
63.55g or 63.55 grams
What part of an atom can be used to determine if two atoms are the same element?
Number of protons.
The number of these must be the same for all atoms of an element?
The number of protons is identical in all atoms of an element.
What must atoms of the same element have?
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
Does an olympic medal contain about twenty thousand billion billion atoms of copper and zinc?
wo i had the same question and its a no
What explain atoms on Mars must be composed of?
Atoms on mars are composed of protons and electrons which are composed of quarks, the same as atoms everywhere in the universe.
What is required for two atoms to share electrons equally in chemical bonds?
the two atoms must be of the same element
What is required for two atoms to share electron equally in a chemical bond?
the two atoms must be of the same element
