List of radioactive elements?
Elements that decay (give off protons and neutrons) to form other elements. *It's not elements as such that are stable or unstable, but rather isotopes. Even elements of small atomic number have unstable isotopes that undergo radioactive decay, for example carbon-14. Elements with higher atomic numbers than Lead (82) are naturally radioactive in all isotopes. Bismuth (83) has an extremely long half-life, but the time generally becomes shorter (the decay more rapid) as the size of the nucleus gets progressively larger for heavier radioactive elements.
What happens to atoms that are radioactive?
Radioactive atoms undergo spontaneous decay, emitting particles or energy in the form of radiation. This process transforms the atoms into different elements or isotopes, creating new elements that may also be radioactive. This decay continues until the atom reaches a stable state.
What is the process in which the atomic nuclei of unstable isotopes release fast moving particles and energy?
The process is called radioactive decay, in which unstable isotopes undergo spontaneous disintegration to form more stable elements. During this process, fast-moving particles such as alpha and beta particles are emitted, along with energy in the form of gamma rays.
What elements that emit atomic particles are called?
Elements that emit atomic particles are typically referred to as radioactive elements. These elements undergo radioactive decay and emit particles such as alpha particles, beta particles, or gamma rays as they try to become more stable.
Do all elements decay over time?
No, not all elements decay over time. Some elements are stable and do not undergo radioactive decay.
What are elements with no stable isotopes called?
Elements with no stable isotopes are called radioactive elements. These elements spontaneously undergo radioactive decay, which leads to the formation of stable isotopes over time.
When an isotope is blank it does not undergo radioactive decay?
When an isotope is stable, it does not undergo radioactive decay. Stable isotopes have a balanced number of protons and neutrons in the nucleus, which prevents them from spontaneously changing into another element over time.
What alkaline earth metal is radioactive?
There are two radioactive alkaline earth metals: radium (Ra) and radium (Ra). Both elements have radioactive isotopes that undergo radioactive decay.
How do radioisotopes of an element differ from other isotopes?
Radioisotopes are unstable isotopes that undergo radioactive decay, emitting particles and/or energy in the process. This distinguishes them from stable isotopes that do not undergo radioactive decay. Radioisotopes are often used in medicine, industry, and research for various applications due to their unique properties related to their decay process.

What is a stable isotope?
A stable isotope is an isotope that does not undergo radioactive decay, meaning its nucleus is stable and does not change over time. These isotopes have a constant number of protons and neutrons, making them suitable for use in scientific studies like tracing biological processes or determining the age of rocks. Examples include carbon-12, oxygen-16, and nitrogen-14.
Why does radon undergo radioactive decay?
No stable isotopes.
Can a natural isotope be radioactive?
Yes, a natural isotope can be radioactive. Some natural isotopes have unstable nuclei and undergo radioactive decay to achieve a more stable form. This process involves the emission of radiation in the form of alpha particles, beta particles, or gamma rays.
Why is silver radioactive?
Silver itself is not radioactive. However, certain isotopes of silver can be radioactive. For example, silver-108 and silver-110 are radioactive isotopes with long half-lives that can undergo radioactive decay. These isotopes are not commonly found in nature.
Why does thorium undergo radioactive decay?
The ratio neutrons/protons in radioactive isotopes is the cause of their innstability.
Are most isotopes stable?
No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
Is radioactivity a curse?
Radioactive isotopes are just elements which have a tendency to undergo alpha, beta or gamma radiation to bring themselves to a stable electron configuration.
