The repitation of physical and chemical properties of elements periodically is called periodicity
periodicity of an elemement is basically repetiton of lemements at regular intervals for example elements of similar properties repeated after 2,8,8,18,32 .
- atomic theory- law of mass conservation- periodicity law- law of multiple proportionsand many others
Organic Chemistry is defined as 'The Chemistry of Compounds of Carbon'.
pure science is best defined as the ?
All amorphous solids are composed of particles with no crystalline structure that has any sort of periodicity, the most common of which, perhaps, is glass. This means that the particles have no ordered arrangement. This is opposed to crystalline solids which do have a well defined periodicity and have long range order.
mendeleev arranged elements according to atomic mass. He was able to observe periodicity when arranged in this pattern.

Mendeleev's Periodic Table -- the reason for periodicity -- is explained by the arrangement of the electrons around the nucleus. *Read your chemistry book* :D

The changes in matter
In a chemistry dictionary one will find a list terminologies and words related to chemistry. Each chemical and element will be defined with its uses explained.
Lack of periodicity means there's no pattern of repeat or recurrence.
Organic is any chemical containing carbon when pertaining to chemistry.
"Chemistry" is a hard word to define. Some chemistry textbook covers show pictures of bubbling flasks, suggesting that chemistry can be defined as "the study of how we can make things behave if we mess with it in the laboratory." Other chemistry books have pictures of huge molecules on the cover, suggesting that chemistry is defined as "the study of how we can cram atoms together to make big complicated structures." I've even seen a textbook cover that featured a multicolored squiggle. I have no idea what that says about the study of chemistry. It seems to me that if we put these two definitions of chemistry together, we get a reasonable idea of what the subject actually entails. Chemistry can be defined as using our knowledge of how matter is put together and how it interacts with other matter to solve confusing problems.
Chemistry is the natural science that studies the structure and behavior of matter at the microscopic scales of molecules, atoms, and subatomic particles.
