gas in radioactivity

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 cal..

A thermal power plant utilizes thermal energy of fuels such as coal, oil, natural gas or radioactive substances for the generation of electric powe..

Noble gases always occur in free state because of their inert nature. All the noble gases, except radon are present in air in small amounts. The relative abundance of the noble gases in air is = 1%. Helium is present in natural gas up to the extent of 10 per cent. It is also present in sm..

Occurrence - Noble gases always occur in free state because of their inert nature. All the noble gases, except radon are present in air in small amounts. The relative abundance of the noble gases in air is = 1%. Helium is present in natural gas up to the extent of 10 per cent. It is also ..

1. It is used for water and gas pipes. 2. It is used for the plates of lead-acid accumulators (batteries). 3. As a screen from radioactive rays. 4. In alloys such as type metal, solder, etc. 5. In bullets. 6. To prepare lead tetraethyl, (C 2 H 4 )Pb which is used as an additive..

Group 17 of the periodic table contains the elements fluorine, chlorine, bromine, iodine and astatine. These elements are collectively known as the HALOGENS. This name is derived from two Greek words Halo and Gens meaning 'salt producing'. Halogens are among the most reactive non-metals. Ther..

Exploration of the planets by space probes has expanded our understanding of the solar system. Modern theories about the earth's origin explore how the earth fits into the solar system, the Milky Way galaxy, and the universe as a whole. Most scientists agree that the earth was probably formed at th..

Energy can be defined as the ability to do work. A good source of energy would be the one which would: do a large amount of work per unit volume or mass be easily accessible be easy to store and transport and be economical Fossil Fuel Fossil fuel is a hydrocarbon deposit, such as petro..

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 rad..

a) Checking the air pollution by strict imposition of laws on factories. b) Reducing vehicular traffic and encouraging public transport vehicles than individual vehicles. c) Use of unleaded petrol. d) Regular check of exhaust gases from vehicles to declare their status in respect of pollution. e) ..
