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.

∙ 9y agoAlthough isotopes of an element do have the same atomic number, they do have different numbers of neutrons. So, this statement is true. For example, the element lithium has isotopes, such as lithium-6 and lithium-7. While lithium-6 has three neutrons, lithium-7 has four neutrons.

∙ 11y agoYes, they do. Isotopes are caused by an atom carrying extra neutrons.
Some radioactive isotopes have fewer neutrons. These decay by positron emission or K capture instead of electron emission during beta decay.

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.
Isotopes of elements?
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
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.
How would you describe the isotopes of hydrogen?
All atoms of a specific element have the same number of protons in their nucleus, but the number of neutrons in the nucleus may vary these are isotopes of that element.Hydrogen has several possible isotopes, only the first three of these are commonly referred to:hydrogen or protium or hydrogen-1, 1 proton 0 neutrons, stabledeuterium or hydrogen-2, 1 proton 1 neutron, stabletritium or hydrogen-3, 1 proton 2 neutrons, radioactive halflife 12.26 yearshydrogen-4, 1 proton 3 neutrons, radioactive halflife about 139 yoctosecondshydrogen-5, 1 proton 4 neutrons, radioactive halflife about 910 yoctosecondshydrogen-6, 1 proton 5 neutrons, radioactive halflife 290 yoctosecondshydrogen-7, 1 proton 6 neutrons, radioactive halflife 23 yoctosecondsetc.
How do radioactive isotopes add to earths heat?
Radioactive isotopes release energy in the form of heat as they break down. Heat itself increases the rate of this break down.

What term describes isotopes with an unbalanced number of neutrons?
Radioactive
Why does thorium undergo radioactive decay?
The ratio neutrons/protons in radioactive isotopes is the cause of their innstability.
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.

What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Can hydrogen be radioactive?
Yes, one of its isotopes, tridium, which has an atomic weight of two and an extra two neutrons its its nucleus, is highly radioactive, as well as rare.
How are radioactive isotopes different from isotopes?
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Isotopes of an element have a different number of?
neutrons
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.
