∙ 9y agoA nucleus with too few neutrons is unstable because there are not enough to keep protons in the nucleus. Due to the small number of neutrons, protons can repel one another from the nucleus making it unstable.

∙ 9y agoToo many neutrons will make a nucleus unstable because of the attractive nuclear force between nucleons (protons and neutrons). This force is different than the repulsive electrostatic force. The nuclear force keeps protons and neutrons at an average separation when in balance with the electrostatic force. When a nucleus becomes heavy with neutrons, this balance is thrown off, and the nucleus becomes unstable.

∙ 6y agoThis depends on the ratio neutrons/protons in the atomic nucleus; when this ratio increase the atom become more and more unstable. Also isotopes with high atomic weight are frequently unstable.

What is radioactive in physics?
the unstable nucleus of an atom
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.
Nuclear radiation refers to charged particles or energy emitted by an unstable what?
Nucleus
In nuclear fission reactions what causes the atom's nucleus to become unstable?
the absorption of a free-moving neutron by the atom's nucleus
What is the definition of a radioisotpoe?
A radioisotope is an atom that has an unstable nucleus characterized by excess energy.
What makes americium radioactive?
Because the nucleus of americium is heavy and unstable.
What quality in uranium makes it useful in nuclear power?
An unstable nucleus which decays emitting a neutron.
What makes an element unstable or radioactive?
The stability of an atom depends on a balance between the numbers of protons and neutrons in its nucleus and also on the total size of its nucleus; atoms with sufficiently large nuclei are inherently unstable. Please see the link.
What makes a nucleus unstabe?
A nucleus with too few nuetrons is unstable because there are not enough to keep the protons. There must be a certain amount of nuetrons for every element.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
What makes trans-uranium elements radioactive?
Transuranium elements are radioactive and unstable; the stability of a nucleus is a problem of nucleon physics.
What happens to a nucleus of an unstable atom?
the unstable nucleus will decay into smaller, stable particles.
The nucleus of a radium 226 atom is unstable which causes the nucleus to?
Decay
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.
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
Magnesium
What is the term for an atom that has an unstable nucleus?
radioisotope
What is radioactive in physics?
the unstable nucleus of an atom
