Everything that exists in our universe is made up of this tiny particle called atom. The computer you are working on is made up of atom..

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..

Question: A zinc rod was kept in a glass container having CuSO 4 solution. On examining, it was found that the blue colour of the solution had faded. After few days when the zinc rod was taken out of the solution, a number of small holes were noticed in it. State the reason and give ..

. Analogous structures are those that show no similarity in the internal structure or anatomy. However, they carry out similar structural or physiological functions. For example, birds and bats both have wings, while mice and crocodiles do not. Does that mean that birds and bats are more closely re..

) who experimented with electricity and made major inroads in understanding the phenomenon. By the middle of the eighteenth century, there were machines that could generate large electrical charges. Static electricity may produce dramatic effects but it is of very little practical use to us. It is ..

Structure of Atom - 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 ab..
