Although Dalton's theory of the existence of atoms was published in 1808 there was no clear idea of what an atom might look like until the early part of the twentieth century. With the advent of electricity and phenomenon of spectrum, experimentation underwent a change and a flu..

Valence Shell and Valence Electron - The outermost shell of an atom is called its Valence shell. It is the decisive shell during a chemical reaction. The electrons of only this outermost shell are involved during chemical combinations; electrons are either given out from the outermost she..

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 m..

Introduction - A story unfolds - Structure of atom : Let us right away meet those who scripted a "mighty story" of a "miniscule" atom. John Dalton (1766 - 1844) : Born in a poor family of a weaver in England, he rose to become a teacher and later a Principal of a schoo..

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 atoms..

Arrangement of Electrons in an Atom (Bohr-Bury Scheme) - Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also..
