An unstable nucleus (radioactive isotope) may emit: alpha particles, beta particles, gamma radiations, electrons, positrons, X-rays, and neutrons, depending on which nucleus is doing the emitting.
What else can I help you with?
Why nucleus is a source of eletromagnetic radiation?
When the nucleus is unstable, one of the ways to reach stability is to emit electromagnetic radiation in the form of gamma rays.
What causes radioactivity?
Radioactivity is caused by the instability of an atom's nucleus. An unstable nucleus can emit particles or energy in the form of radiation in order to become more stable. This process is known as radioactive decay.
Can unstable atoms have a nucleus that always remains the same?
No, unstable atoms cannot have a nucleus that always remains the same. By definition, unstable atoms undergo radioactive decay, which means their nuclei change over time as they emit particles or radiation to reach a more stable state. This process alters the composition of the nucleus, leading to the transformation of one element into another or the release of energy. Therefore, the nucleus of an unstable atom is inherently dynamic and subject to change.
What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Where do the two neutrons and two neutrons that consist on alpha particle come from?
they come from the nuclei of an unstable atom.

What causes radioactivity?
Radioactivity is caused by the instability of an atom's nucleus. An unstable nucleus can emit particles or energy in the form of radiation in order to become more stable. This process is known as radioactive decay.
What is the spontaneous process through which unstable nuclei emit radiation?
The spontaneous process in which unstable nuclei emit radiation is called radioactive decay. During this process, the unstable nucleus releases energy in the form of alpha particles, beta particles, or gamma rays in order to become more stable.
Why are isotopes radioactive and what factors contribute to their ability to emit radiation?
Isotopes are radioactive because they have an unstable nucleus, which means they have an imbalance of protons and neutrons. This imbalance causes the nucleus to emit radiation in the form of alpha particles, beta particles, or gamma rays. Factors that contribute to their ability to emit radiation include the number of protons and neutrons in the nucleus, as well as the energy levels of the particles within the nucleus.
Can unstable atoms have a nucleus that always remains the same?
No, unstable atoms cannot have a nucleus that always remains the same. By definition, unstable atoms undergo radioactive decay, which means their nuclei change over time as they emit particles or radiation to reach a more stable state. This process alters the composition of the nucleus, leading to the transformation of one element into another or the release of energy. Therefore, the nucleus of an unstable atom is inherently dynamic and subject to change.
Where does radioactivity start in an atom?
Radioactivity starts in an atom's nucleus, specifically when the nucleus is unstable and tries to become more stable by emitting particles such as alpha or beta particles, or energy in the form of gamma rays. This process is known as radioactive decay.
What is property in which unstable nuclei of an element spontaneously emit radiation?
Radioactivity is the property in which unstable nuclei of an element spontaneously emit radiation.
What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
What radiation does a nucleus with more than 82 protons usually emit?
A nucleus with more than 82 protons is usually unstable and may emit alpha or beta radiation to become more stable. This process helps lower the number of protons and neutrons in the nucleus, bringing it closer to a more stable configuration.
Where do the two neutrons and two neutrons that consist on alpha particle come from?
they come from the nuclei of an unstable atom.
What is a nucleus that is unstable and undergoes decay?
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
Can gama radiation takes place before alfa and beta decay?
Yes. Each unstable element decays differently. Some emit gamma, some emit alpha, some emit beta, and some emit different combinations of those in different sequences as one unstable element gives rise to another unstable element.
