What is make an atom isotope?
It is the neutron that makes changes in atomic nuclei to change them from one isotope to another. For any given element, that element will have a fixed number of protons. It is, after all, the number of protons that determine the elemental identity. But the number of neutrons in a given element can vary, and we use the term isotope to talk about which particular atom we're investigating. That is, we apply the term isotope to speak to an atom of a given element with a certain number of neutrons in its nucleus.
If the isotope have short half lives is that mean that the isotope is in a stable condition?
No. Only radioactive elements have half-lives, the half-life is the time that it will take for half of the atoms in a sample of a radioactive isotope to decay into another element or isotope. This is a constant property of the isotope and does not depend on the sample size. Stable isotopes never decay.
What is half of a radioactive isotope mean?
Half of a radioactive isotope refers to its half-life, which is the time required for half of the isotope's atoms in a sample to decay into a different element or isotope. During this period, the radioactivity decreases exponentially, meaning that after one half-life, 50% of the original isotope remains, and after two half-lives, 25% remains, and so on. This concept is crucial in fields like radiometric dating, nuclear medicine, and understanding radioactive decay processes.
How is a radioactive isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
How do you calculate the atomic weight of a chemical element that has two or more isotopes?
To calculate the atomic weight of an element with multiple isotopes, you multiply the mass of each isotope by its relative abundance (as a decimal), then sum the products. The result is the atomic weight of the element, which is a weighted average of the masses of its isotopes based on their abundance in nature.
What is another term for an atom that is unstable?
isotope
What is the term for elements that have different numbers of neutrons?
Isotope
What is a general term for any isotope of any element?
The word substance is used in chemistry to describe elements or compounds. It is used because when dealing with an unknown substance, it is important to not assign either name to it.
A general term for any isotope of any element?
Nuclide
What is the term for an atom that contains a different number of electrons and protons?
An isotope.
What is the term for the element that a radioactive isotope decay into?
The term for the element that a radioactive isotope decays into is called the "daughter product". During radioactive decay, the original isotope transforms into a different element or isotope through a series of decay reactions.

What is meant by th term effective half life of a radioactive isotope used in medicine?
when it ends.
What does it mean when the isotope is fissile?
"Fissile" means "capable of undergoing fission."
What is the term for the time required for half of a parent isotope to decay into a daughter product?
it's half life
Term for an atom that has the same atomic number as another atom but differs in atomic weight?
This is the definition of an "isotope".
How many isomer in nuclear physics?
Isomer is the term used for chemical compounds having the same molecular formula, in physics the term isomer is meaningless although the term Isotope is used.
