Question

an element X changes to another element Y write the emission of beta particles write down the equation showing changes in the nucleus take the proton number and mass number of X as Z and A respectively​

Answer 1

Answer:

When A zX loses first β-particle atomic number of daughter nucleus Y increases by  remains the same When A z+1X loses another β-particle changes to daughter . An element X loses one α- and two β- particles in three successive stages. Successive emission of an alpha-particle and two beta-particles by an atom
