4.what is stabilised rule.
2. The Microscopic world is the system which has the small scale(size), of order of atomic dimension (about 10 A or less), and it characterizes the properties of individual particles, but Macroscopic world is the system which has the large scale (size) which can be seen with ordinary sense (of order of one micron) and it characterize the system as as whole.
Atomic phenomena: Those phenomena that take place within the atome are called atomic phenomena.
