What planets and celestial bodies seem to be radioactive?
Stars seem to be, but they don't have big and/or unstable atoms such as most radioactive elements have. They release sub atomic units when their atoms fuse, along with rays such as gamma rays, which is why they can seem to be similar to other radioactive things. Some planets with atmostpheres that are ionised by ionising rays can also be similar to radioactive things perhaps.
What are the 2 characteristics of matter?
mass and atoms
Does radioactive mean in science?
The atoms structure is unstable and it emits alpha or beta particles that changes the Atom
What do scientists use to measure the absolute age of a rock?
Finding the age of rocks based on the presence of naturally occurring long-lived radioactive isotopes of several elements in certain minerals and rocks.Many rocks and minerals contain radioactive atoms that decay spontaneously to form stable atoms of other elements. Under certain conditions these radiogenicdaughter atoms accumulate within the mineral crystals so that the ratio of the daughter atoms divided by the parent atoms increases with time. This ratio can be measured very accurately with a mass spectrometer, and is then used to calculate the age of the rock by means of an equation based on the law of radioactivity. The radioactive atoms used for dating rocks and minerals have very long half-lives, measured in billions of years. They occur in nature only because they decay very slowly. The pairs of parents and daughters used for dating are listed in the table.(see also the related link)The age of a rock may be determined by analysis of the matter it contains. Many minerals have radio active half lives that can be used to determine roughly how long ago the rock was formed. Another indication may be the type of fossils found in sedimentary rocks.
What is the smallest unit of matter with unique characteristics?
That would be an atom. Atoms go down to protons, neutrons and electrons, but these do not have unique characteristics. So, the smallest particle with unique characteristics is an atom.
Which atoms are least likely to be radioactive?
Generally, the smaller the nucleus, the less radioactive.
Atoms that are unstable are more likely to be what than atoms that are stable?
radioisotopes
What is meant by radioactive metal?
It means that it's (a) a metal, and (b) radioactive. Radioactivity refers to certain types of atoms (certain isotopes) breaking down, converting into other types of atoms. In the process, they release energy, and certain types of radiation.
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.
