Radioactive Decay or Disintegration - A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioa..
Radioactive Decay or Disintegration - A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioa..Nuclear Stability and Neutron/Proton Ratio
The stability linked to the n - p ratio is explained by strong n - p as well as p - p attractive forces operative at the level of nuclear distances. For heavier nuclides, p - p repulsions start to offset the attractive forces and an excess of neutrons over protons is required for stabilit..

Properties of alpha particles
They are deflected by electric and magnetic fields. The deflection is less compared to that of b particles, because a particles are heavy. They affect a photographic plate and cause fluorescence on striking a fluorescent material. They ionise the gas through which they pass. The mass..

Radioactivity
It is a spontaneous emission or disintegration of an unstable nucleus resulting in certain radiations. The elements exhibiting this phenomena are called radioactive elements. e.g., radium, thorium, actinium, polonium etc. Radioactivity does not occur due to any external provocation and is a propert..

Naturally occurring radioactive substances have high nucleon number. It is possible to make artificial radioactive substances by bombarding lighter nuclides with - particles, protons or neutrons. The radioactive substances produced in this manner are known as radioisotopes. A nuclide is a..

Radioactivity Spontaneous emission of active rays by certain unstable elements. Three types of radiations are: (i) Alpha particles He 2 + ion (Helium nuclei). (ii) Beta - rays - consist of electrons. (iii) Gamma - rays - High energy electromagnetic rays. Emission of alpha..

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.
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.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
