No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
An unstable atom that decomposes and emits energy is radioactive. An electrically charged atom or group of atoms are called ions.
FALSE, an unstable atom that decomposes and emits energy is called radioactive.
radioactive, or radioisotope.
Radioactive.
Radioactive isotopes.
no
true
radioactive
Both. Electrons absorb energy and move to a higher energy state, which is unstable, and they fall back down to their ground state immediately, releasing energy as they do.
The numbers listed represent the first, second and third energy levels, respectively. On this basis, which of the following is an unstable or reactive atom? 2, 8, 1
Depends on the isotope can be 0 or 1 hydrogen is a highly unstable element that the electron Jumps betweent the two energy levels
When electrons change energy levels they usually become more stable. Sometimes when electrons change energy levels they become unstable though.
This would be radioactivity in which alpha or beta particles are released. The nucleus concerned decays into another nucleus with lower energy, resulting in ejection of the particle which has kinetic energy, until it is absorbed into some other material which will happen quite quickly. See the link below for more discussion of the energy changes
This is a radioactive isotope.
Radiation
They obtain energy in much the same way as people do. They take organic matter called detritus, and take the chemical potential energy out of it.
The elements described are said to be radioactive.
The more unstable an atom the more likely it is to lose energy. The process atoms losing energy this way is called radioactive decay.
yes. glucose metabolises and decomposes to form carbon dioxide, water with the release of energy
Ambient heat
A radio-isotope.
Radioactive decay
They are all required to drive the carbon/energy cycle.
Gamma rays.
process of unstable atoms trying to become stable by emitting energy that is at a level high enough to ionize
