Isotopes of the same element are determined based off the number of neutrons the atom has which is directed related to the atomic mass of the element( the more neutrons the greater the mass of that atom). Because you can not change the number of protons in an atom without changing the element, scientist differentiate isotopes based off the Atomic Mass of the isotope.
What else can I help you with?
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 element has the atomic mass of 22?
An isotope of Neon. This isotope accounts for between a fifth and a quarter of the element.
How do you know the difference between isotopes and an element?
Isotopes are atoms of an element having different number of electrons.
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 many neutrons calcium?
The number of neutrons is the difference between the Atomic Mass of an isotope and the atomic number of the element; each isotope of calcium has a different number of neutrons. See the link below for calcium isotopes.
How do you find the number of neutrons an isotope has?
Neutron is the difference btw the atomic no and the mass no of an element.
What and the difference between an atomic symbol and a chemical symbol?
An atomic symbol represents a specific isotope of an element, including both the element symbol and the atomic mass number. A chemical symbol, on the other hand, is just the unique abbreviation for an element on the periodic table.
How many neutrons does Krytpon-82 have?
The answer to how many neutrons an atom of an isotope has is always the difference between the mass number of the isotope and the atomic number of the element. The atomic number of krypton is 36. Therefore, an atom of krypton-82 has 46 neutrons.
What is the relationship between a nuetron and an isotope?
Isotopes of an element has different number of neutrons.
What the difference between radioactivity and half life?
An isotope of a chemical element is an atom that has the same number of protons (this also means this atom has the same atomic number) and electrons, but has a different numbers on neutrons. The isotope is radioactive if it has too many neutrons in the nucleus and because of this the isotope is unstable. The half-life of a radioactive isotope is a time period. When the isotope is at the end of the period it's weight will be the half of the starter weight.
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.
