No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.

Do the colors of flame tests result from taking in energy or releasing energy?
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.
What numbers are an unstable or reactive atom?
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
How many electrons are in the second energy level of hydrogen?
Depends on the isotope can be 0 or 1 hydrogen is a highly unstable element that the electron Jumps betweent the two energy levels
What happen when electron change energy level?
When electrons change energy levels they usually become more stable. Sometimes when electrons change energy levels they become unstable though.
What makes glow stick chemicals react?
The two chemicals in glow sticks are hydrogen peroxide and phenyl oxalate ester. The chemical reaction for this kind of heatless light happens when you mix multiple chemical compounds. When you combine two or more compounds, the atoms may rearrange themselves to form new compounds. Depending on the nature of these compounds, this chemical reaction will cause either a release of energy or absorption of energy. You activate a glow stick is by bending, and then shaking it. When you bend it, a very fragile glass vial inside of it breaks and releases the chemical inside (hydrogen peroxide) to mix with the other substance (phenyl oxalate ester). When these are combined they go through a chemical reaction (oxidation), which makes a different, unstable chemical, called peroxyacid ester. This new unstable substance decomposes into a different compound, (phenol and a cyclic peroxy compound) and then to carbon dioxide. The energy caused by the decomposition makes the particles in the fluorescent dye move faster and this creates light. The color of the fluorescent dye determines what color the light will be. This process is called chemiluminescence.
What is an unstable atom that emits energy called?
This is a radioactive isotope.
The release of energy when a nucleus decomposes?
Radiation
How do decomposed obtain energy?
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.
What are unstable elements that give off energy as they decay called?
The elements described are said to be radioactive.
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.
Is glucose a source of energy?
yes. glucose metabolises and decomposes to form carbon dioxide, water with the release of energy
The least unstable form of energy is?
Ambient heat
An unstable isotope with extra energy in the nucleus?
A radio-isotope.
Process by which unstable nuclei lose energy?
Radioactive decay
What are the roles of producers consumers decomposes in an ecosystem?
They are all required to drive the carbon/energy cycle.
A penetrating ray of energy emitted by an unstable nucleus?
Gamma rays.
Is the process of unstable atoms trying to become stable by emitting energy that is at a level high enough to ionize.?
process of unstable atoms trying to become stable by emitting energy that is at a level high enough to ionize
