What else can I help you with?
Do all isotopes only occur in heavier elements?
No, isotopes of light elements exist as well. For example, there are several isotopes of the lightest element, hydrogen.No, even the lightest element (hydrogen (H)) has isotopes. These are called Deuterium and Tritium.All elements have isotopes but some of them are very unstable and have disappeared in nature over time.
Does every element has two stable isotopes?
No, Gold and several other elements have only one stable isotope, Promethium & Technetium as well as all elements heavier than Bismuth have no stable isotopes.
What is the different of isotopes and a same element?
Isotopes are atoms of the same element that are only different by the number of neutrons they have
Which diagrams represent isotopes of the same element?
Only some special diagrams represents isotopes of the same element.
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.
Which alkali metal element has no stable isotopes?
Elements with no stable isotopes include technetium (element 43) and promethium (element 61) and all elements heavier than lead (elements 83 and higher). Bismuth, element 83, is virtually stable with an extremely long half life of 1.9 x 1019 years.
What can you say about the basis difference in isotopes?
Isotopes of the same element ONLY differ in mass.
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).
What is the lightest element on the periodic table with no stable isotopes?
The lightest element on the periodic table with no stable isotopes is hydrogen. It only has one proton in its nucleus and no stable 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.
Can 2 isotopes of the same element differ in the number of electrons?
No. The only difference between 2 isotopes of the same element is the number of neutrons.
Why isotopes of the same element are not considered different elements?
Isotopes of the same element have the same number of protons, which is what defines an element. The only difference between isotopes is the number of neutrons in the nucleus. Since isotopes of an element have the same chemical properties, they are not considered different elements.
