What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
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 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.
If the nucleus of a radium-226 atom is unstable what causes the nucleus to spontaneously decay?
Instability is due to a certain ratio between neutrons and protons in the atomic nucleus.
Any atom containing an unstable nucelus?
An atom containing an unstable nucleus is called a radioactive atom. These atoms emit radiation as they decay in order to become more stable. The emitted radiation can be in the form of alpha particles, beta particles, or gamma rays.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
What are the characteristics of a atom?
A radioactive atom is an atom of an element with an unstable nucleus.
What is the term for an atom that has an unstable nucleus?
radioisotope
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.

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
A free-moving neutron is absorbed by the nucleus of an atom. This can cause?
the atom to become unstable and rip apart
What is radioactive decay in your own words?
It is when an atom's nucleus contains too many neutrons and becomes too unstable. Thus, the nucleus "wants" to become more stable and thus splits into two lighter nuclei. To get rid of the extra neutrons that were making the atom unstable, when the atom splits apart, these neutrons are ejected outwards. The two split nuclei become two separate, more stable atoms.
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 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 number of protons does carbon atom become unstable?
Carbon atom contains only 6 protons. It is become unstable when number of neutrons are increasing.
