What is it when naturally unstable elements release particles from the nuclei and give off heat?
It is called radioactivity.
Why is decay necessary?
Those elements undergo the 'decay' process which have unstable nuclei so decay is necessary to gain the stability. such elements form the smaller stable nuclei as Lead nucleus.
How many unstable nuclei exist in nature?
Around 1500 unstable nuclei (or radioisotopes).
Why radioactive materials are unstable?
Radioactive metals are unstable as their nuclei is large and do not have a strong binding force as the smaller elements. If a neutron is collided onto a radioactive nuclei, they split into smaller atoms like Uranium splits into Barium and Krypton. Since they are unstable, they have a half life of varying times which range from the age of the earth to nanoseconds for recently discovered elements
What is the difference between a stable and unstable nucleus?
In most atoms the protons and neutrons found in the nucleus are held together strongly. The nuclei of these atoms are said to be stable. However, the neutrons and protons in some atoms are not held together as strongly. These nuclei are unstable and will eventually disintegrate, forming other elements. Isotopes that are unstable are said to be radioactive and are called radioactive isotopes or radioisotopes.
Where do the two neutrons and two neutrons that consist on alpha particle come from?
they come from the nuclei of an unstable atom.
LArge nuclei are unstable because?
Penis
How do nuclear atoms differ from regular atoms?
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."
Unstable atomic nuclei decay over time into stable nuclei causing a mineral to be?
radioactive
Where is unstable nuclei most commonly found?
AFRICA
Radioactivity is produced when unstable nuclei .?
Break apart
Why do very large nuclei tend to be unstable?
Bukkake
