Average Atomic Mass, or Atomic Weight of an element (the one shown on the Periodic Table).
What else can I help you with?
There are no known stable isotopes of the element with an atomic number of a 56 B 38 C100 D 20?
The element with an atomic number of 100 is Fermium (Fm), which does not have any stable isotopes. Fermium is a synthetic element that is produced in nuclear reactors and has only radioactive isotopes. Stable isotopes have a balance of protons and neutrons that result in a nucleus that does not undergo radioactive decay.
Atoms of the same element with different atomic masses?
Isotopes are atoms of the same element with different atomic masses, characterized by the number of neutrons in the nucleus. Despite having different masses, isotopes share the same number of protons and electrons. Certain isotopes may be unstable, leading to radioactive decay.
What are atoms called if they have the same number of protons but different number of neutrons?
An atom of an element having the same number of protons (as well as electrons) but a different number of neutrons is known as an isotope. Isotopes are often used in the nuclear power industry. An example of an industry is "heavy water" or Deuterium Oxide. It is water but with and isotope of hydrogen that has 2 extra neutrons. The isotope is called Deuterium, and heavy water is also sometimes known as D2O.
Can the number of neutrons for an element ever differ?
Absolutely. An element is defined by the number of protons in the atomic nucleus. For example, any nucleus with a single proton is by definition hydrogen. There are, however, three different forms of hydrogen; the kind with no neutrons (which is the most usual form), one neutron (known as deuterium) and two neutrons (known as tritium). Every element has isotopes with varying numbers of neutrons.
Are all atoms of a given element identical to one another and different from atoms of other elements?
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
What are atoms of the same element with different masses called?
These are known as isotopes.
Are iron elements stable?
Iron is an element, and there is only one element called iron (Fe). There are no iron element(s), but if you mean isotopes, then some iron isotopes are stable, and some aren't. No known element is stable in of it's isotopes.
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 weighted-average mass of all the known isotopes for an element?
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.
Is the weight average mass of all the known isotopes for an element?
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.
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).
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
Does isotopes only occur on heavier element?
No - the lightest element Hydrogen has three known isotopes
Atoms of the same element that differ in the number of neutrons they contain are known as?
they are known as isotopes. Dont ask people to do your homework
What is the name for atoms of an element that have different masses?
An atom or element that have different masses are known as isotopes.
What are element that differ in the number of neutrons known as?
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
What are atoms element that have a different number of neutrons known as?
Isotopes
