energy and fast-moving particles are released,
Unstable nuclei are most commonly found in radioactive materials, such as uranium and radium. These materials emit radiation as the unstable nuclei undergo radioactive decay in an attempt to become more stable.
There are many unstable nuclei that exist in nature, but the exact number is difficult to determine due to the sheer variety of radioactive isotopes that can occur. These unstable nuclei can undergo radioactive decay to become more stable over time.
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance, leading to radioactive decay.
Radioactive decay
The ore containing unstable nuclei is D) Pitchblende. Pitchblende, also known as uraninite, is a primary ore of uranium and contains radioactive elements with unstable nuclei. Gypsum, feldspar, and magnetite do not contain such unstable nuclei and are not radioactive.
It's Nuclei, the past answers are wrong.
All atoms are nuclear, in that they all have nuclei. Some atoms have unstable nuclei, making them radioactive. I'm afraid I have no idea what you mean by "nuclear atoms," unless you meant to say radioactive atoms, in which case the answer is "they have unstable nuclei and they're radioactive."
Yes, radioactive objects emit heat as a byproduct of their radioactive decay process. This heat is produced by the energy released during the decay of unstable atomic nuclei.
Radioactive decay is the process in which unstable nuclei release radiation in the form of alpha particles, beta particles, or gamma rays.
unstable and eventually transform into a stable form. This process is known as radioactive decay and can result in the mineral changing its chemical composition or structure.
