Atomic nuclei with more than 84 protons or a large neutron-to-proton ratio is unstable. These nuclei will lose alpha-particles (generally reduces the nucleus by 2 protons and 2 neutrons) or beta-particles (generally turns a neutron to a proton) until it becomes stable. This can take billions of years or a fraction of a second, depending on the isotope.

Why only radioactive element give out radiation?
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Is radioactive radiation an element compound homogeneous mixture or heterogeneous mixture?
Hydrogen is an element.
True or false unstable atom that decomposes and emits energy is called retroactive?
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
What are the requirements for something to be radioactive?
The substance in question must be relatively unstable and be emitting subparticles.
What results when radioactive decay causes loss or one more protons?
A new Element is formed -Shakainn👌
What is the effect of radioactive pollutions on humans?
Radioactive pollution causes cancer.
What king of decay causes geothermal heat?
radioactive
What causes heat in center of earth?
Radioactive Decay
What causes transmutation?
Nuclear decay or radioactive bombardment.
What causes radioactives pollution?
The release of radioactive substances in the atmosphere leads to radioactive pollution. Only the radioactive wastes cause the radioactive pollution. Nuclear material is pure and they are not the factor for causing radioactive pollution. The waste discarded improperly only causes radioactive pollution.The following causes the radioactive pollution in high rangeNuclear power plantsCoal fired power plantsUranium plantsThe above said power plants release radioactive wastes to the atmosphere. During their release or transportation of radioactive wastes, the radioactive pollution occurs.
Which causes maximum radioactive contamination out of there sodium radium potassium?
Radium, by a big margin. Radium has no isotopes that are not radioactive, but no naturally occurring isotopes of potassium or sodium are radioactive.
Were can you find a radioactive spider?
There are no radioactive spiders. This is something from a movie, and has never happened. There is no way to find images of radioactive spiders.
How do you use radioactive as an adjective in a sentence?
You can just put something in the sentence that is going to be radioactive that's all.
What causes a poop attack?
When you swallow radioactive food and it comes alive
How can radioactive contamination occur?
Radioactive contamination is also known as radiological contamination. It is the deposition, or presence of radioactive substances on surfaces within solids, liquids, or gases. There presence is unintended or undesirable.
Why only radioactive element give out radiation?
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Is rabbit feces radioactive?
No. There is no reason why rabbit feces should be radioactive, unless of course they ate something radioactive or they are under medical care using radioactive isotopes. It might be possible that if the soil is radioactive, and the plants become radioactive, that a rabbit might excrete radioactive feces from eating the plants.
