only one isotope of element X occurs in nature. One atom of this isotope has a mass of 9.123x10-23g. What is the molar of the element X?
Isotopes are different forms of an element that have the same number of protons but different numbers of neutrons. These different numbers of neutrons can result in different atomic masses. Only one isotope of an element is found in nature because it is the most stable form of that element and has the most balanced ratio of protons and neutrons. Other isotopes may be created in laboratories or through natural processes, but they are not as stable and tend to decay quickly.
The number of neutrons in an isotope can affect its stability, radioactivity, and chemical reactivity. Isotopes with a larger number of neutrons tend to be less stable and more likely to undergo radioactive decay. They may also have different chemical properties, such as a different atomic mass or a different number of electrons in the outer shell, which can affect how they interact with other elements.
Yes, some elements can have multiple isotopes found in nature. However, only one isotope of an element is typically dominant and most abundant. This is because the other isotopes may be less stable and decay over time, leaving the dominant isotope as the only one remaining in nature.
No, while all isotopes of an element have the same number of protons, they may have different numbers of neutrons, which can affect their chemical properties. This is especially true for heavy elements, where the number of neutrons can greatly impact the stability and reactivity of the isotope.
Isotopes of an element can be identified and distinguished through their atomic mass. This is because the atomic mass is determined by the number of protons and neutrons in an atom. Therefore, isotopes with different numbers of neutrons will have different atomic masses. Scientists can use various techniques, such as mass spectrometry, to measure the atomic mass and identify different isotopes of an element.
