uses of isotopes atoms

. When the plant or animal dies fresh carbon is no longer taken in and the C - 14, which is present, decays. Thus, the length of time a specimen has been dead may be determined by the activity of the C - 14, which remains in it. Carbon - dating has therefore become an important tool for archaeologi..

. This is known as ocean thermal energy. Small scale experiments have shown that it might be possible to build large ocean thermal energy systems but they would be quite expensive. Different seas have different concentrations of salt. When two seas meet, electricity can be produced by making u..

Hydrogen atom (Z=1) has no neutrons. Number of protons = 1 Number of electrons = 1 Number of neutrons = 0 It has been reported that the hydrogen element has atoms with mass number 2 and 3 also i.e., Atoms of elements having the same atomic number with dif..

Nuclear Fission - Two consequences of nuclear reactions are the phenomena of nuclear fission and nuclear fusion. Both are important sources of nuclear energy, which may be used for peaceful or destructive purposes. When a nucleus is bombarded with some sub-atomic particles such ..

>When a nucleus emits radiation it is said to decay. Rays from radioactive isotopes are dangerous to living things but are also useful in variety of ways. Exposure to large amounts of radiation is harmful to health. All radioactive materials should always be handled with care an..

a) Metal casting can be tested for cracks by putting them in baths of radioactive salts. The castings are then inspected for radioactivity to find out any penetration of salts into cracks. Absence of salt penetration indicates absence of cracks. b) Radioactive isotopes can be used..

Thus this phenomenon in which artificial transmutation of a stable non - radioactive nucleus leads to the formation of radioactive isotope is called artificial radioactivity or induced radioactivity. Some of the isotopes produced as a result of neutron bombardment find applicati..

Advantages of Long form Periodic Table - 1. The classification of elements is based on the atomic number, which is a more fundamental property. 2. The reason for placing isotopes at one place is justified as the classification is on the basis of atomic number. 3. It ex..
