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.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
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.
When an unstable isotope produces a particle and energy it can change the number of protons in the nucleus. This creates?
An atom of a different element.
Where do the two neutrons and two neutrons that consist on alpha particle come from?
they come from the nuclei of an unstable atom.
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.
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 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
What is radioactive in physics?
the unstable nucleus of an atom
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
What happens to a nucleus of an unstable atom?
the unstable nucleus will decay into smaller, stable particles.
What is a characteristic of a radioactive nucleus?
A radioactive atom is an atom of an element with an unstable nucleus.
What causes an atom to be stable and unstable?
If an atom has more protons then electrons the atom will have a negative charge.If the atom has more electrons then protons the atom will have a positive charge.If the atom has equal numbers of electrons and protons then the atom becomes neutral.However if you're wondering why an atom is stable then that means that it has all the electrons inside of it paired. If the atom is unstable it has unpaired electrons.
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.
A free-moving neutron is absorbed by the nucleus of an atom. This can cause?
the atom to become unstable and rip apart
Where does radioactivity start in an atom?
radioactivity start from the nucleus of an atom which becomes unstable n emit radiation
