When scientists started exploring matter, they discovered that the smallest particle of an element that maintains its chemical identity through all chemical and physical changes is called and 'atom'. Just how small these atoms are can be made out if you realize that there are about 60,000,000,000,..

Mendeleev's Periodic table simplified the study of elements. As the arrangements of elements showing similar properties were classified into groups, it was very useful in studying and remembering the properties of a large number of elements in a systematic wa..

It is interesting to note that n/p ratio of lighter elements is around one, whereas for heavier metals it is higher. Higher the n/p ratio, more unstable is the element. That is why metals like uranium and polonium are unstable and radioacti..

We shall now study about the exact relation between the force applied and the motion of the object on which the force is applied. This was studied by Sir Issac Newton. He gave the three basic laws of motion concerning objects in moti..

The structure of the cell that we have studied so far is that of a eukaryotic cel..

Archimedes' studied the upthrust acting on a body, when it is partially or completely immersed in a fluid by performing several experiments and then stated the following principle known as the Archimedes' Princip..

Comparative morphology involves the study of the external features of organisms. There are three types of evidences that comparative morphology reveals. They ar..

Atoms are infinitesimally small. Smaller than any thing we can imagine. One hydrogen atom, the smallest atom known, is approximately 5 x 10 -8 mm in diameter. To put that in perspective, it would take almost 20 million hydrogen atoms to make a line as long as this dash ' - '. The extremely small si..

Importance of Classification - By making a comparative study and assorting the similarities and differences amongst the various varieties of species, organisms can be classified into groups or sets. Taxonomy is a regular branch of science that is involved with the purpose of arr..

Introduction - You have studied in the previous chapter about refraction of light by lenses and also about the nature, position and relative size of images formed by lenses. How can these ideas help us in the study of the human eye? The human eye uses light and enables us to see..
