particle nature of electrons

Particle Nature of Light - According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron m..

/c to photons of energy h u . The elastic scattering of a photon from an electron at rest can be worked out by using the principles of conservation of energy and conservation of momentum. The discovery in 1905 of the dual nature of light was followed by the discovery of dual ..

An electron is defined as a subatomic particle which carries one unit of electrical charge (1.602 x 10 - 1 9 C) and has a mass (9.1 x10 - 2 8 g). The mass of an electron is almost negligible, being 1/1837 t h the mass of an atom of hydrogen. The charge of an h..

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 centur..

Electronic Nature of Metals - Metals are the elements which form positive ions by losing electrons, while non-metals always gain electrons. All metals (except hydrogen) form positive ions by loosing electrons. Metals have 1 to 3 electrons ..

Metals are the elements which form positive ions by losing electrons, while non-metals always gain electrons. All metals (except hydrogen) form positive ions by loosing electrons. Metals have 1 to 3 electrons in the outermost shell of their atom and non-metal..

Electronic Nature of Metals and Non-metals - We are familiar with the fact that the atoms of all elements, except noble gases, have an incomplete outermost shell. Consequently, most elements are reactive and they try to achieve the stability of the noble or inert gases by e..

Dual Nature of Matter and Radiation - Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It ..
