An isotope is a form of an element. Isotopes (forms of an element) occur when an atom/s of a single chemical element gains or loses 1 or more neutrons.
Eg.. the first isotope "Hydrogen-1" or "Protium" hydrogen has 1 proton in the centre of the atom or nucleus, and 1 electron going around on the outside, isotope two "Hydrogen-2" or "Deuterium" Hydrogen, has 1 proton AND 1 neutron in the nucleus and 1 electron, and isotope three is "Tritium" Hydrogen that has 1 proton, 2 neutrons and 1 electron. The number of protons always stays the same, it's the number of neutrons that determines the form of an element or in other words the isotope.

∙ 10y agoAn isotope can be thought of as a subtype of an element. All atoms of an element have the same number of protons - that's what mainly determines their chemical properties. Atoms which have the same number of protons but a different number of neutrons are said to be different isotopes of the same element.

What term describes isotopes with an unbalanced number of neutrons?
Radioactive
Do most elements occurs a mixture of two or more isotopes on nature?
For elements the correct term is atomic weight.For isotopes the correct term is atomic mass.The atomic weight is determined considering the isotopic composition of an element and the atomic mass of each isotope.
Mass number of first 20 elements?
Mass number is term used for isotopes, not for elements. And it is boring to list here all the isotopes of the first 20 elements.
Number of isotopes in lithium?
lithium has 7 isotopes
How many stable isotopes does hydrogen have?
Hydrogen has three isotopes
What is the medical term meaning injection with radioactive isotopes?
brain scan
Which term describes atoms with different atomic masses due to varying numbers of neutrons?
Isotopes (Pretty Sure)
What term describes isotopes with an unbalanced number of neutrons?
Radioactive
What is a stable isotope?
Stable isotopes are chemical isotopes that are not radioactive, meaning that they do not spontaneously undergo radioactive decay.
Are ions isotopes atoms the same thing?
No. Isotopes are a subset of atoms, for elements which have more than one isotope. The term isotope has meaning only in comparison to another atom with the same atomic number, while the more general term atom is not so limited. Ions differ from both of the others by being electrically charged.
Is plutonium a nonrenewable resource?
On long term, the useful isotopes of plutonium are not renewable.
Define the term isotope explain how two isotopes of an element are different?
Isotopes are atoms of the same element that have different numbers of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers. I hope I helped! ^_^
What term would you use to classify the two substances of how their atomic mass and atomic number?
They are isotopes.
What is the medical term meaning faint?
Syncope is the medical term meaning fainting.
What is the Medical term meaning deafness?
Anacusis is the medical term meaning complete deafness.
What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
Muscle term meaning shortest?
The term is Brevis, meaning shortest.
