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.
What makes a nucleus radioactive?
If you are referring to a cell's nucleus than the simple answer is that's not radioactive. Radioactivity occurs when elemental atoms become unstable due to the loss or gain of additional neutrons; these unstable atoms are referred to as radioactive isotopes. If a cell's nucleus were radioactive it would not last very long, its structure and function would quickly degrade and collapse.
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
What happens to the nucleus when a neutron hits it?
When a neutron hits the nucleus, it can be absorbed by the nucleus, causing the nucleus to become unstable and possibly undergo radioactive decay. This process can lead to the release of energy, emission of radiation, or transmutation of the nucleus into a different element.
Which particle is emitted from a hydrogen-3 nucleus when it undergoes radioactive decay?
When a hydrogen-3 nucleus undergoes radioactive decay, it emits a beta particle (specifically an electron) and an anti-neutrino to transform into helium-3.

What happens during radioactive decay apex?
An unstable nucleus loses particles until it becomes stable.
What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
Which are unstable elements that decay or break down into differt elements?
Unstable elements that decay or break down into different elements are called radioactive elements. These elements have an unstable atomic nucleus that undergoes radioactive decay, transforming into a different element and releasing energy in the process. Examples of radioactive elements include uranium, radium, and plutonium.
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
What happens to a nucleus of an unstable atom?
An unstable nucleus can undergo radioactive decay to become more stable. This can involve emitting radiation in the form of alpha particles, beta particles, or gamma rays. The decay process results in a transformation of the nucleus into a different element or isotope.
What do you call an element with unstable nucleus?
Radioactive isotope, or radioisotope.
What terms best describes the nucleus of a radioactive element?
unstable
Is this true radioactivity and radioactive decay are two distinct phenomena?
True and False. Radioactivity is a characteristic of unstable atomic nuclei, whereas radioactive decay is the process that a radioactive nucleus undergoes when it decays due to its instability.Argument for true: Radioactivity is the tendency to undergo radioactive decay.Argument for false: The two terms are unrelated because one is a characteristic and the other is a process, and, therefore, the question misunderstands the definition of the terms.You choose your definition. This writer prefers false.
What is a characteristic of a radioactive nucleus?
A characteristic of a radioactive nucleus is that it undergoes spontaneous decay, emitting radiation in the form of alpha particles, beta particles, or gamma rays in order to achieve a more stable configuration.
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
When an unstable magnesium nucleus undergoes gamma decay, it remains as a magnesium nucleus. Gamma decay does not change the atomic number or mass number of the nucleus, only releasing a gamma photon to reduce excess energy.
