Differentiate between nuclear reaction and chemical reaction
Answers
Answer:
# Nuclear reactions involve a change in an atom's nucleus, usually producing a different element ,along with the emission of radiations. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. So nuclear reaction is nuclear phenomenon and chemical reaction is extra-nuclear phenomenon.
# Different isotopes of an element normally behave similarly in chemical reactions as their extra-nuclear electronic configurations are same. The nuclear chemistry of different isotopes vary greatly from each other.
# Rates of chemical reactions are influenced by external effect like temperature,pressure and catalysts. Rates of nuclear reactions are spontaneous and are unaffected by such factors.
#Nuclear reactions are independent of the chemical form of the element.This means both in elemental and in compound state same amount of radio-element shows similar radioactivity.
# Energy changes accompanying nuclear reactions are much larger. This energy comes from destruction of mass.
#In a nuclear reaction, mass is not strictly conserved. Some of the mass is converted into energy,according to the equation E = mc2 and the order of energy evolved during a nuclear reaction is much higher than that of a chemical reaction.
