Having an unstable nucleus means that the nucleus of an atom has an excess of energy or mass, making it prone to decay or transformation into a more stable form. This instability can lead to the emission of radiation in the form of alpha particles, beta particles, or gamma rays as the atom seeks a more stable configuration. Unstable nuclei are often found in radioactive isotopes, which can undergo spontaneous decay over time. This process is a key aspect of nuclear physics and has implications for both natural phenomena and applications like nuclear medicine and energy.
What else can I help you with?
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.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
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.
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
What aspects of the composition of a nucleus can cause it to be unstable?
The two aspects that cause the nucleus of any element atom to be unstable are:not have the specific neutron/proton ratio to be a stable nucleus, and orhaving number of protons that exceeds the stability limit (exceeding 83).Referring to question below for more information.

What makes a nucleus unstable?
The strong nuclear force doesn't balance the electrostatic force.
How is a stable nucleus different to an unstable nucleus?
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
What it means when an element is radioactive?
Radioactive elements have unstable nucleii. When an unstable nucleus decays it emits energy in the form of electromagnetic waves and heavy particles and in the process forms new nucleii.
What is the term for an atom that has an unstable nucleus?
radioisotope
Nuclear radiation refers to charged particles or energy emitted by an unstable what?
Nucleus
What is natural transmutation?
Change from unstable to stable nucleus.
Is radioactivity caused due to unstable nucleus?
Yes.

If an element is radioactive is it's nucleus unstable?
Yes,The element is radioactive due to the instability of its nucleus.See the related question below for more information.
