Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioactive and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.

How many stable isotopes are in the element californium?
All the isotopes of californium are radioactive, artificial and unstable.
How many isotopes of gallium are there?
There are two stable isotopes of gallium: gallium-69 and gallium-71. Additionally, there are several radioactive isotopes of gallium, but they are unstable and decay over time.
How many isotopes does copper have?
Copper has natural isotopes of 63,67. And other isotopes are known at least from 58 through 70. But these are unstable.
What is the difference between a stable isotope and a unstable isotope?
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.
How many isotopes does boron have?
Two stable ones, 10 & 11. Several unstable.

Is gallium a naturally occurring isotopes?
Yes, gallium does have naturally occurring isotopes. The most common stable isotopes of gallium are gallium-69 and gallium-71, with gallium-69 being more abundant at about 60% and gallium-71 about 40%.
How many isotopes does boron have?
Two stable ones, 10 & 11. Several unstable.
How many neutrons are in an atom he?
In total nine different isotopes of helium are known to exist. Helium 3 (one neutron) and helium 4 (two neutrons, by far the most common isotope) are the only stable isotopes. The other 7 isotopes (helium 2, 5, 6, 7, 8, 9, and 10) are unstable and rapidly decay into stable isotopes.
Why do isotopes become unstable?
An isotope is unstable because isotopes are only atoms with a change in the number of neutrons. For an atom to become stable, it should have the maximum number of electrons it can have in its outer most shell, but since isotopes only deal with neutrons, this problem is not dealt with in this case. When there is a change in the number of electrons, it is called a ion. It can become stable through ionic bonding, covalent bonding and metallic bonding, depending on the two elements that are meant to bond.
What is it meant by the term stable isotope?
Stable isotopes do not undergo nuclear decay. Hydrogen has three isotopes, two are stable and the third is unstable. They are ;_ protium; 1 proton , 0 neutrons and 1 electron (Stable) The commonest isotope of hydrogen. deuterium ; 1 proton , 1 neutron and 1 electron (stable). Also known as 'heavy hydrogen - used to make heavy water). tritium ; 1 proton , 2 neutrons, and 1 electron (unstable - undergoes radio-active decay).
What are three different isotopes in nitrogen?
Nitrogen has two stable isotopes: N-14 and N-15 and 14 radioactive isotopes.
How many chlorine has isotopes?
Chlorine has a lot of different isotopes but the 2 stable ones are chlorine 35 and chlorine 37
What are the names of the of the unstable hydrogen isotopes?
The only UN-stable Hydrogen isotope is Tritium, atomic number 1 (of coarse!), mass number 3, with 2 neutrons in nucleus, beta- electron emitter, (max.) 0.018 MeV, half-time 12.3 yr.
