Discovery of Neutrons
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, it was possible to calculate the char..
Artificial Nuclear Reactions
Artificial Nuclear Reactions - Radioactivity is broadly classified into two categories: a) Natural radioactivity and b) Artificial or Induced radioactivity. If a substance emits radiations by itself, it is said to possess natural radioactivity. If a substance does not possess radioactivity but star..

Summary - When certain metals are heated to a high temperature, they emit thermions (electrons) and the phenomenon is called thermionic emission Cathode rays are a stream of negatively charged particles emitted from the cathode of an evacuated bulb, when a voltage of nearly 3000 volts given across ..
Structure of the Atom
Structure of the Atom - Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J. Tho..
Structure of Atom Summary
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 discovery of ..
Characteristics of Beta Rays (i.e., b - Particles)
Beta rays are made up of streams of negatively charged particles similar to electrons. Thus, - particle has a unit negative charge and a negligible mass. They are electrons. Hence, - particle is represented as -1 e 0 . They affect photographic plate. They get deflected to the maximum e..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
