different concepts of structure of atom

A Search for the Particles of Atom of Electrons - 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 phen..

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..

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

(except helium which has two). Atoms of the same element having same atomic number but different mass numbers are called isotopes. Isotopes show similar chemical properties but different physical properties due to the difference in the number of neu..

In order to explain the stability of an atom Neils Bohr in 1913 proposed a new theory to explain the arrangement of electrons in an atom. According to Neils Bohr, the electrons could revolve around the nucleus only in 'certain orbits' (energy levels), each orbit having a d..

The compounds can be branched when the carbon atoms are more than three . Some of the examples are: Name Formula Number of carbon atoms..

The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutrons. As the protons are ..

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..

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..
