Isotopes with unstable nuclei are?
Unstable Isotopes will degrade through radioactive decay into other types of atoms. To break it down Unstable isotopes are those whose moleules break down to form new atoms and ions.
What are mass of unstable atoms?
Unstable atoms are said to be radioactive
Which atoms will always be radioactive?
Almost all the lower elements in the periodic table will always be radioactive.
Will the radioactive property remain in an ionic compound when a metal element is highly radioactive combined with a non-metal element which is non-radioactive?
A radioactive material is radioactive. Period. The atoms of radioactive material have unstable nuclei. If you combine them with other material, the radioactive material will remain unaffected as regards its radioactivity. Recall that radioactivity is related to the instability of atomic nuclei, and the atomic structure of atomic nuclei are (in general) not involved in chemical bonding. Chemical bonding doesn't affect the stability of the nuclei of atoms. If they are unstable, they will remain so whether the atoms are alone or chemically combined with something else.
What is it called when an unwanted material that contains radioactive atoms is present on another material?
Radioactive Contamination
Atoms with certain characteristics are radioactive Which is least likely to be radioactive?
all atoms with an atomic number under 40
Atoms that are unstable are more likely to be what than atoms that are stable?
radioisotopes
Isotopes with unstable nuclei are?
Unstable Isotopes will degrade through radioactive decay into other types of atoms. To break it down Unstable isotopes are those whose moleules break down to form new atoms and ions.
What is likely to happen to atoms like plutonium with many neutrons and a heavy nucleus?
Radioactive disintegration or spontaneous fission
Do radioactive atoms have different atomic weights than non radioactive atoms of the same element?
yes
How do nuclear atoms differ from regular atoms?
All atoms are nuclear, in that they all have nuclei. Some atoms have unstable nuclei, making them radioactive. I'm afraid I have no idea what you mean by "nuclear atoms," unless you meant to say radioactive atoms, in which case the answer is "they have unstable nuclei and they're radioactive."
Are radioactive atoms stable?
No
How are energy loss and nuclear stability related to radioactive decay?
The more unstable an atom the more likely it is to lose energy. The process atoms losing energy this way is called radioactive decay.
What must occur before a radioactive atoms ceases to undergo further radioactive decay?
A stable, nonradioactive atom must be formed.
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
What happens to atoms that are radioactive?
Its nucleus emits radioactive particles continuously.
What are mass of unstable atoms?
Unstable atoms are said to be radioactive
