uses of isotopes atoms

The number N A , given by N A = 6.023x10 2 3 mol - 1 is called Avogadro's number, named after Italian scientist Amadeo Avogadro (1776-1856), who suggested that all gases contain the same number of atoms or molecules when they occupy the same volume under the same conditions of temper..

It is used for welding purposes in both the oxy-hydrogen torch and the atomic-hydrogen torch, when temperatures of the order of 2500C and 4000C are required respectivel..

It is used as a reducing agent in industry and laboratories. It is used to prepare hydrogenated vegetable oils. It is used for welding purposes in both the oxy-hydrogen torch and the atomic-hydrogen torch, when temperatures of the order of 2500C and 4..

Radioisotopes are frequently used as tracers or tagged atoms in various fields. In tracer technique, a radioactive isotope is added to the reactants and its movement is studied by measuring radioactivity in different par..

This classification is based on the most fundamental property of the elements - the atomic number, so it is more accurate. With the atomic number as the basis of this classification, the position of isotopes in one place is justified. The systematic grouping of..

Cl - 35.5Cu - 63.5The fractional atomic masses of elements are due to the existence of isotopes having different mass..

When four different atoms are attached to the chiral carbon, priority depends on atomic number. The atom with the highest atomic number gets top priority. If the two atoms are isotopes of the same element, the atom of highe..

Later on, an atom of oxygen was preferred as standard by taking its mass as 16 units. In 1961, the international union of chemists selected the most stable isotope of carbon (C-12 isotope) as standard for comparison. For example, if 1 atom of Na weights as m..

10. Calculate the average atomic weight of silicon having 92.2% of Si-28 isotope of relative mass 27.98 amu, 4.7% of Si-29 isotope of relative mass 28.98 amu and 3.1% of Si-30 isotope of relative mass 29.97 am..

The optical microscopes developed in physics are extensively used in the study of biological samples. Electron microscope, X-rays and radio isotopes are used widely in medical scienc..
