Comparison of Dalton's Atomic Theory and Modern Atomic Theory
Dalton's Atomic Theory Modern Atomic Theory All matter is made up of extremely small particles called atoms An element is made up of extremely small particles called atoms Atoms are indivisible and indestructible ..
Modern Atomic Theory
In view of new discoveries about atoms, Dalton's atomic theory was modified as given below: Atom is no longer indivisible as it has a complex structure of sub atomic particles (electrons, protons and neutrons). Atoms of the same element may posses d..
Modern definition of atomic mass unit
The mass of 1/12 part of 12 C isotope of carbon is equivalent to one atomic mass uni..
Trends in the Modern Periodic Table
The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom..
The Modern Periodic Table
Modern Periodic Table-Long Form Periodic Table of Elements - Later, Henry Gywn-Jeffreys Moseley showed that the atomic number of an element is numerically equal to the number of electrons round the nucleus. The number of electrons in turn is equal to the number of protons in the..

The periodic trends of the following properties are studied here. Atomic size Metallic and Non-metallic character Ionization potential Electron affinity Electronegativit..
Modern Physics Introduction
Introduction - You have learnt in the earlier chapters that flow of electrons constitutes an electric current and current can be generated from a battery or a generator. Scientists later discovered that there are many other ways of producing the stream of electrons. This knowledge has led to furthe..
Long Form of the Periodic Table or Modern Periodic Table
With developments on the structure of atoms, it was discovered that the atomic number (Z) is the important characteristic of the atom and not the atomic mass. This led to the development of the modern periodic law by Moseley in 1942. The ..
