An isotope is an element that has the same number of protons and a different number of neutrons, whereas a nuclide is a specifically defined isotope.
Quite literally, they refer to the exact same atom, but the difference lies in the definition. Nuclides are defined by many different aspects, such as half life, mode of decay, percent abundance, and so on. The Chart of the Nuclides is a very extensive reference for the characteristics of over 3000 different isotopes.
The term isotope is merely a way of differentiating between an atom that is the same element (same number of protons) but has varying numbers of neutrons.

What is the name of the daughter nuclide?
The daughter nuclide is the new isotope formed from the radioactive decay of a parent nuclide.
Is a parent isotope more radioactive then a daughter isotope?
Yes, a parent isotope is typically more radioactive than its daughter isotope because it undergoes radioactive decay to form the daughter isotope. The rate of decay for the parent isotope will be higher, leading to a higher level of radioactivity.
Which of the following could be a correct nuclide symbol for an isotope of vanadium (V)?
5123V or V-51
What is the number of neutron is equal to?
The number of neutrons of an isotope is the difference between the mass number of the isotope and the number of protons (equal to atomic number).
An isotope of uranium using nuclide notation?
The chemical symbol of uranium is U.
What is the name of the daughter nuclide?
The daughter nuclide is the new isotope formed from the radioactive decay of a parent nuclide.
A general term for any isotope of any element?
Nuclide
What is a nuclide symbol?
A nuclide symbol represents a specific isotope of an element and consists of the element's chemical symbol, atomic number, and mass number. The chemical symbol is a one- or two-letter abbreviation for an element, the atomic number is the number of protons in the nucleus, and the mass number is the sum of protons and neutrons in the nucleus.
Is a parent isotope more radioactive then a daughter isotope?
Yes, a parent isotope is typically more radioactive than its daughter isotope because it undergoes radioactive decay to form the daughter isotope. The rate of decay for the parent isotope will be higher, leading to a higher level of radioactivity.
What is the nuclide symbol for calcium-41?
The nuclide symbol for calcium-41 is ^41Ca. This notation indicates the element (Ca for calcium) and the mass number (41) of the isotope.
Which of the following could be a correct nuclide symbol for an isotope of vanadium (V)?
5123V or V-51
What is the symbol of the nuclide having 16 protons and 16 neutrons?
The nuclide with 16 protons and 16 neutrons would have an atomic number of 16 and a mass number of 32. The symbol for this nuclide would be 32S, representing sulfur.
Nuclear decay is the change of an atom of...?
... an unstable isotope to a more stable isotope by emission of some type of radiation (alpha, beta, or gamma).
What type of radioactive nuclide is injected into a person who is about to undergo a PET scan?
The radioactive nuclide typically used in a PET scan is fluorine-18, which is commonly attached to a glucose molecule to form fluorodeoxyglucose (FDG). This radiotracer is injected into the patient and accumulates in tissues with high metabolic activity, allowing the PET scanner to detect areas of increased glucose uptake, such as in tumors.
How many subatomic particles are in a nuclide?
The atom of a chemical element contain protons, neutrons and electrons; the number is specific for each 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.
Which of the following could be a correct nuclide symbol for an isotope of vanadium?
One correct nuclide symbol for an isotope of vanadium could be ^51V.
