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?
Atoms with stable nuclei are least likely to be radioactive. Typically, atoms with an even number of protons and neutrons are more stable and less likely to undergo radioactive decay. This includes elements such as carbon-12, oxygen-16, and nitrogen-14.
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.
Atoms that are unstable are more likely to be what than atoms that are stable?
Atoms that are unstable are more likely to be radioactive than atoms that are stable. This means they can emit radiation in the form of alpha or beta particles, or gamma rays, in order to reach a more stable state.
Which atoms will always be radioactive?
There is no specific atom that will always be radioactive. Any atom with an unstable nucleus can be radioactive, resulting in the emission of radiation. Isotopes of certain elements, such as uranium and plutonium, are more likely to be radioactive due to their relatively large atomic numbers.
Do all atoms give out radiation?
No, not all atoms give off radiation. Only certain types of unstable atoms, known as radioactive atoms, undergo radioactive decay and emit radiation in the form of alpha particles, beta particles, or gamma rays.
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
Is diamond radioactive?
No, diamonds are not radioactive. They are made up of carbon atoms arranged in a crystal structure, which does not contain any radioactive isotopes. However, some diamonds may have trace amounts of radioactive materials if they were formed in certain geological environments, but this is not typical or significant. Overall, diamonds are considered safe and non-radioactive.
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
Powerful energy emitted from certain heavy atoms?
This powerful energy is likely referring to nuclear radiation emitted by radioactive heavy atoms, such as uranium or plutonium. This radiation can take the form of alpha particles, beta particles, or gamma rays, and can be harmful to living organisms if not properly contained or shielded against.
