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 Radioactive decay or disintegration. When..

Two batches of 100 animals were tested in a drug research lab. One batch was given an antiviral injection and all the animals in the two batches were exposed to viral infection. The table gives the numbers of dead and survived animals. Dead Survived Inoculated 15 85 No..

Ammonia is produced by decay of plant and animal tissues. Nitrogenous organic matters like urea in the urine and excreta of animals get acted upon by bacteria releasing ammoni..

Protons and neutrons Nuclear forces Electromagnetic repulsion between the protons Nuclear fusion and fission reactions Radioactive isotopes Three most common forms of radioactive decay (alpha, beta, gamma) Changes in the nucleus in each type of decay ..

Ammonia (NH 3 ) is an important compound of nitrogen and hydrogen. It is produced by the natural decomposition of animal and vegetable bodies. The death and decay of plants and animals cause the nitrogen compounds present in them to get decomposed, giving ammonia. Ammo..

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 ..

The half-life of 92 U 238 against alpha decay is 4.5 x 109 years. How many disintegrations per second occur in 1 g of 92 U 238 ..
