Is copper a stable element?
stableAnswer:Like many elements copper has many isotopes. Two of these are stable (63Cu and 65Cu) others are radioactive. The isotope with the longest half life is 67Cu with a half-life of almost 62 hours.
What is a similarity and a difference between isotopes of an element?
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
The following atoms are all variations of the element carbon. 12c 13c and 14c. what are theses variations called?
The following atoms are all variations of the element carbon 12C 13C 14C what are these variations called isotopes. Isotopes are variants of a particular chemical element.
The various atomic weights of the same element are called?
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
Is a copper door with knob a compound element or mixture?
If all the components are made from pure copper - yes, all is from the chemical element copper.
The average mass of all the known isotopes of an element is what?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.

What is the average of all the naturally occurring isotopes of a particular element?
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
Plus how are all of the isotopes of an element similar?
All the isotopes of a chemical element have the same number of protons and electrons (in a neutral state).
How do the atomic number of the different isotopes an element compare?
The atomic number is the same for the all isotopes of a chemical element.
What element is memeber of this group all isotopes of this element are radioactive?
There is no group specified so it is not possible to be sure about this answer but all isotopes of promethium are radioactive.
What is a similarity and a difference between isotopes of an element?
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
Do isotopes exist independently to form an element or do all the isotopes when combined constitute an element?
The ratio of isotopes are constant throughout the universe. In any random sample of any element, there will be a consistent ratio of isotopes of that element. This is what makes radiocarbon dating of ancient organic material possible.
Why is the atomic mass of copper not exactly equal to 64 midway between the mass numbers of copper-63 and copper-65?
Because copper has isotopes. All Copper atoms have exactly the same number of protons, but not all of them have the same number of neutrons. The ones with different numbers of neutrons are known as isotopes. A given sample of Copper will contain various amounts of each of its isotopes. The atomic mass (weight) is an average weight, based on the percentages of the isotopes
What is an element that is the average mass of all the isotopes of that element?
This is a chemical element with a specific atomic weight.
