Regular elements contain regular neutron number and the same number of protons and neutrons. Isotopes have different neutron numbers than the original element, but the same number of protons and electrons.
What else can I help you with?
What element has the atomic mass of 22?
An isotope of Neon. This isotope accounts for between a fifth and a quarter of the element.
What factors contribute to the physical differences between one isotope of a particular element and another?
The physical differences between isotopes of an element are mainly due to variations in their atomic mass, which is determined by the number of neutrons in the nucleus. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to differences in stability, radioactivity, and chemical behavior.
What are differences between ions and isotopes?
An ion is an atom with an electrical charge, positive or negative.An isotope of chemical element is an atom having a different number of neutrons.
What is the relationship between a nuetron and an isotope?
Isotopes of an element has different number of neutrons.
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
What percentage of an atom's mass is the nucleus?
The precise figure varies from element to element and isotope to isotope depending on the number of neutrons in the nucleus, however it is always at least 99.95% which is the ratio between an electron and a proton.
What is the difference between an atom an isotope and an ion?
an ion is when an element loses or gains one or more electrons. an isotope is when a element loses or gains one or more neutrons. when one or more proton(s) is/are gained or lost, it becomes a different element.
What best describes a radioisotope?
its nucleus is unstable
An isotope shares the atomic number with its element atom How does it differ from the element atom?
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
What is an atom called when the number of neutron changes?
An atom with a different number of neutrons is called an isotope of the original element. Isotopes have the same number of protons (and thus the same element) but different numbers of neutrons.
What is the difference between the parent isotope and the daughter isotope?
The parent isotope is the original radioactive isotope that undergoes decay to form the daughter isotope. The daughter isotope is the stable isotope that is formed as a result of the radioactive decay of the parent isotope.
How do you find the atomic number of an isotope?
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.
