In nuclear fission reactions what causes the atom's nucleus to become unstable?
the absorption of a free-moving neutron by the atom's nucleus
How do control rods stop a fission reaction?
Control rods have a large neutron absorption cross section. That means that they slow down, absorb, and effectively stop neutrons. In order to sustain a fission reaction, you need a certain number of neutrons of a certain energy interacting with fissile material at a certain rate so that everything is in equilibrium. When you insert the control rods, you bring the core geometry to a sub-critical state, what we call KEffective < 1, and the fission reaction stops.
Why does spectrum of light happen?
White light is a mix of different frequencies; with certain equipment, it is possible to separate it into its components. This separated version is called a "spectrum".White light is a mix of different frequencies; with certain equipment, it is possible to separate it into its components.

Are gamma rays best for cell phone transmission?
No. Gamma rays are extremly energetic rays; too difficult to control. X-Rays, which are weaker than gamma rays, have certain uses in technology, but hardly for communications.
When a certain isotope such as Pa-231 is hit by a neutron it will always split into the same smaller nuclei?
false
Can you get a rash from certain Chinese herbs?
It is possible to have an allergic reaction to anything if your body recognizes it as something that will harm it.
Is it possible to be allergic to seedless watermelons?
its possible, what type of reaction do you have. Some people get migrains from certain fruit, and some fruit makes people's skin hurt
Does the ion enable a neutron to change into a proton and an electron in certain unstable atoms?
no
In nuclear fission reactions what causes the atom's nucleus to become unstable?
the absorption of a free-moving neutron by the atom's nucleus
What makes a fission reaction possible is that certain atoms are?
Fissile, that is they will split on capturing a neutron, releasing energy. Also if the fission releases more neutrons, as with U-235 and Pu-239, this gives the possibility of a chain reaction.
Why thermal neutron has greater chance to induce fission?
The thermal neutron is possibly the most energetic and powerful form of radiation. Apart from extensive alpha particle bombardment in certain fissile nuclides, neutrons are the only particle which effectively sustains a chain fission reaction.
What would happened to a stable nucleus in which the number of neutrons suddenly decreased?
The nucleus would become unstable because you need a certain amount of neutrons, electrons, and protons for it to be stable.
Is CaCl2 a single displacement reaction?
CaCl2 is not a reaction, but a compound. It can react with certain substances such as Mg.
Does an atom still react even if it has completed its octet?
Normally, not, because all of its valence electrons are occupied. However, under certain conditions, such as high temperature, it is possible to force a reaction.
What are three words that have the same meaning as steady?
synonyms - certain , constant , durable antonyms - unstable , weak , unsteady
Use the term radioactive decay in a sentence?
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."
How can a asteroid get out of a asteroid belt?
An asteroid can get out of the belt because of another huge asteroid hitting it or by getting pulled into an unstable orbit by the gravity of Jupiter. There are gaps called Kirkwood gaps in the asteroid belt at certain distances from the sun because the influence of Jupiter causes orbits at those distances to become unstable. A collision with a comet would be another possible reason, but this is very unlikely (except in Hollywood movies).
