![]() All the elements with Z > 83 (Z is the atomic number) exhibit some type of nuclear activity such as spontaneously emitting particles and/or electromagnetic radiation. In the basis of nuclear reactions is the instability of large atomic nuclei. Now, when one element changes into another, very often tremendous amounts of energy is released. This process is also known as transmutation. The pairing, and the bonding change but there are no new elements appearing in the products.Ĭontrary to chemical reactions, nuclear reactions are associated with changes in the atomic nuclei. ![]() This can be seen in acid-base, precipitation, redox, and in any other chemical reaction:ĢHNO 3 + Ba(OH) 2 → Ba(NO 3) 2 + 2H 2O( l)ģC 2O 2 2- + Cr 2O 7 2- + 14H +( aq) → 6CO 2 + 2Cr 3+ + 7H 2O( l)ĢAgNO 3( aq) + CaCl 2( aq) → 2AgCl( s) + Ca(NO 3) 2( aq) In the context of today’s topic, the key here and in any other chemical reaction is that the elements do not convert into other elements. For example, the reaction between sodium metal and chlorine gas is an example of a redox reaction where the chlorine being more electronegative takes the electron from the metal thus forming a cation and anion which are then boned by an ionic bond: In all the chapters we covered so far, we dealt with chemical reactions where the changes occur as a result of electron redistributions.
