There are no known stable isotopes of the element with an atomic number of a 56 B 38 C100 D 20?
Element 20 is Tin. Element 38 is Strontium. Element 56 is is Barium. Element 100 Fermium. Fermium is artificially created, and has no stable isotopes. In general, there are no stable isotopes heavier than Bismuth (element 83).
Atoms of the same element with different atomic masses?
what is an atom of the same element with different mass numbers
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.
How many elements are there in an atom of sulfur?
there are 210 known isotopes in the element of sulfur i found this on sulfur factrs periodic table of the elements
What are atoms of the same element with different masses called?
These are known as 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.
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.
Is the weight average mass of all the known isotopes for an element?

What are element that differ in the number of neutrons known as?
Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.
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.
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
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 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
Atoms of the same element having different sums of protons and neutrons are called?
These atoms are called isotopes.
