Atomic structure - 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, exper..

Structure of the Atom - The Structure of the Atom Scientific investigation on the structure of atom and its subatomic particles is an area where still absorbs scientists. In the process, they have discovered many more new subatomic particl..

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..

The Structure of the Atom Scientific investigation on the structure of atom and its subatomic particles is an area where still absorbs scientists. In the process, they have discovered many more new subatomic particles, for example positron, meson, quarks ..

Atomic Number, Mass Number or Nucleon Number - The nuclei of atoms are made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the numbe..

The evidence of the electrical nature of matter preceeded the first theories about the structure of matter. In 1832, Michael Faraday discovered electrolysis. He gave the first important clue relating electricity to matter and about the electric nature of atoms..

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..

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 a..

Isotopes - It is interesting to note that atoms of a given atomic number can have different number of neutrons. Some examples are listed belo..
