Chemistry Dictionaries. There are seven oxo acids of nitrogen are known. Keturakis, in Comprehensive Inorganic Chemistry II (Second Edition), 2013. Most of the metals and non metals are soluble in nitric acid.For this reason, nitric acid is also known as aqua fortis, its mean ‘strong water’. Wikipedia … We'll learn more about the definition of these … (1) Complex compounds-definition-examples-perfect-imperfect complex definition. Paramagnetism . Diamagnetism Definition and Examples. I.E. These tabulated values can be problematic since many sources contain incomplete and conflicting data. Diamagnetic atoms have only paired electrons, whereas paramagnetic atoms, which can be made magnetic, have at least one unpaired electron. Examples: NH 3 is diamagnetic because all of the electrons in NH 3 are paired. Definition: Descriptive term which indicates that a substance contains no unpaired electrons and thus is not attracted to a magnetic field. In many metals this diamagnetic effect is outweighed by a paramagnetic contribution, the origin of which is to be found in the electron spin. Return to top of page. Nonetheless, true paramagnets are those materials that show magnetic susceptibility with respect to the Curie law.
