what is Radio activity plzzzz explain??
Answers
Hey !!
RADIO ACTIVITY
Spontaneous decay of unstable nuclei by emission of certain sub particles like α , β and γ radiation is called natural radio activity.
In general natural radio activity occurs i heavy nuclei which tend to become stable. The nuclei which can be transformed into radioactive nuclei by various means is called artificial radioactivity. Regarding radioactivity
It is completely unaffected by the physical and chemical conditions to which the nucleus is subjected, we cannot change the radio activity by applying high temperature, high pressure and strong electric field etc.
A nucleus can disintegrate immediately or it may take infinite time. Hence, we can define a probability for the number of nuclei that may disintegrate in a given time interval.
The energy liberated during the radioactive decay comes from within individual nuclei.
GOOD LUCK !!
Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. ... The most common types of radiation are called alpha, beta, and gamma radiation, but there are several other varieties of radioactive decay.
