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.
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
What is an unstable atom?
An unstable atom is a radioactive atom.
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 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
The nucleus of a radium 226 atom is unstable which causes the nucleus to?
Decay
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
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 a characteristic of a radioactive nucleus?
A radioactive atom is an atom of an element with an unstable nucleus.
In a nuclear fission reaction a freely moving neutron is introduced to a nuclear fuel such as uranium-235. What happens next?
a neutron is absorbed by an atom’s nucleus. (apex)
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.
