Radioactivity
Radioactivity - It is a spontaneous emission or disintegration of an unstable nucleus resulting in certain radiations. The elements exhibiting this phenomena are called radioactive elements. e.g., radium, thorium, actinium, polonium etc. Radioactivity does not occur du..
Radioactive Decay or Disintegration
Radioactive Decay or Disintegration - A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity..
Radioactive Decay or Disintegration - A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity..Radioactivity
The phenomenon of spontaneous disintegration of an unstable nucleus of naturally occurring isotope accompanied by emission of active radiations line a , b and g radiations is known as Natural Radioactivity. These radiations come from the breakup of the central core or nuclei of heav..
Rate of Radioactive Decay
Rate of Radioactive Decay - The spontaneous breaking up of the nucleus is known as radioactive disintegration or radioactive decay. Radioactive disintegration is found to obey the following two laws: i) Atoms of all radioactive e..
Radioactive Decay Series
Radioactive Decay Series - The emission of a or b - particles from a radioactive element results in the function of new element called daughter element. If the daughter element still has unstable nucleus, it further disintegrates by emitting a or b - particle and produ..
Radioactive Decay Series
The emission of a or b - particles from a radioactive element results in the function of new element called daughter element. If the daughter element still has unstable nucleus, it further disintegrates by emitting a or b - particle and produces a new daughter element. This ..
Alpha Decay
Alpha decay is the phenomenon of emission of an a - particle from radioactive nucleus...
Discovery of Radioactivity and Nature of Radiations
In 1896, the phenomenon of radioactivity was accidentally discovered by French scientist Henri Becquerel. He was performing experiments with uranium compounds. He accidentally placed a crystal of potassium uranyl sulphate over photographic plate wrapped with usual black paper. On develo..
Nuclear Stability and Neutron/Proton Ratio
. Thus stable nuclei (non-radioactive) have n/p ratio between 1 - 1.6. These lie in the shaded region of the plot which is also called stability belt or stability zone. The elements whose nuclei do not fall within the stability zone are said to be unstable. The unstable nuclei, whose n/p ..
Radioactive Dating
All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in an artefact..

This is a great help for my son, who is getting help with all major subjects like math, science and English...
Getting Home work help from online everyday helping me a lot to understand my math much better...
I am Jessica from New York, I got excellent English tutors from Tutor Vista, who helped me lot to overcome my grammar mistakes, Thanks a lot...
Their whiteboard is great. Online tutoring from this site is as good as like face to face tutoring and the great thing is I dont have to spend a lot.
