No. isotopes are radioactive because the ratio of protons to neutrons is not right. As proton # increases, more and more neutrons are needed to maintain nuclear stability. If an atom has too many, or too few neutrons, it will be radioactive. Excess (or deficient) electrons are call ions.

What is the meaninq of two isotopes stable and unstable isotopes?
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 man protons does an element have to have to make it radioactive?
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.
Isotopes of elements?
Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
What kind of particle have a unequal number of protons and neutrons?
An isotope is a particle that has an unequal number of protons and neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons. These variations in the number of neutrons result in different atomic masses for isotopes of the same element.
What is the meaninq of two isotopes stable and unstable isotopes?
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.
Why does thorium undergo radioactive decay?
The ratio neutrons/protons in radioactive isotopes is the cause of their innstability.
How man protons does an element have to have to make it radioactive?

How many neutrons does Ar element have?
That depends on the isotope, as Argon has three different stable isotopes and many different radioactive isotopes.
When do radioactive isotopes occur?
A radioactive isotope is an unstable atom which emit radiations as alpha, beta, gamma, neutrons, positrons etc.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
Is boron radioactive?
There are no radioactive isotopes of boron that are ordinarily found in nature. All elements have synthetic radioactive isotopes, however.
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
What kind of particle have a unequal number of protons and neutrons?
An isotope is a particle that has an unequal number of protons and neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons. These variations in the number of neutrons result in different atomic masses for isotopes of the same element.
How do the isotopes of an atom differ?
Isotopes of an atom have the same number of protons but different numbers of neutrons. This causes isotopes to have different atomic masses. The chemical properties of isotopes are usually identical, but physical properties such as nuclear stability and radioactive decay can vary.
How do two isotopes differ from one another?
Isotopes of the same element differ in the number of neutrons. Isotopes of different elements differ in the number of protons and neutrons. For instance, carbon-12, a stable form of carbon, has 6 protons and 6 neutrons. Carbon-14, a radioactive form of carbon that occurs in nature, has 6 protons and 8 neutrons. Nitrogen-16, on the other hand, also radioactive and occurring in the primary coolant of nuclear power plants, has 7 protons and 9 neutrons.
