Search for the missing particle - Although Rutherford's model was enormously successful at explaining the scattering of alpha particles, there was a problem when the experimental data were used to calculate the mass of the nucleus. From the results of the scattering experiments,..

Electricity and Matter - It is important to know the atomic picture of matter. The basic unit of all matter is an 'atom'. Each atom consists of a small core called nucleus which accounts to most of its mass consisting of positively charged protons and neutral neutrons and surrou..

It is the central core of the atom where the entire +ve charge and mass is concentrated. It is a tiny sphere of diameter ranging from 10 - 1 5 m to 10 - 1 4 m. A nucleus is made up of particles called neutrons and protons. A neutron does not carry any char..

Question: Name the fundamental particles whose relative charge is a) +1 b) - 1 C) 0 Answer: +1 proton - 1 electron 0 neutro..

A symbol represents one atom of an element. Example: H stands for one atom of hydrogen. However, if a symbol has a subscript and a superscript, as given along side, then more in formation can be derived from it...

Travel in straight linesThey cast a shadow of the objects placed in their way. Produce mechanical effectA paddle wheel placed in their path starts rotating. Rays are positively chargedWhen an electric field is applied in the path of anode rays, they are deflected towards the negat..

The b - particles are electrons - 1 e 0 with mass number zero and charge equal to -1. Since nucleus does not contain electrons, the emission of b - particle from a radioactive nucleus is believed to arise from the conversion of a neutron into proton and elect..

>Lead-214 decays with the emission of a - particle. The equation for charge is 82 - (-1) = 82 + 1 = 93. But the nucleus is supposed to be made up of protons and neutrons only, so how can a - particle be emitted? A neutron in the nucleus has changed into a ..

Mass Energy Relation - Einstein derived a formula given the relation between mass and energy as E = mc 2 . Here 'm' is the mass, 'c' is the velocity of light and 'E' is the energy. This equation has given equal states to mass and energy. It states that a mass m has energy E given by the above formu..

Summary - Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J. Thomson led to the discovery of electron. Goldstein's experiment with the discharge tube having a perforated cathode led to the dis..
