• D. A - 3,4; B - 1; C - 5; D - 4,2

Answer 1

The correct option is A A - 5; B - 3,4; C - 1; D - 2

• Converting a stable atom into a suitable radioactive element is called artificial radioactivity.
• Nuclei and its decay product have the same difference of n and p i.e., (n−p)=m−2Z(n−p)=m−2Z, hence isodiaphers.
• An atom bomb is weapon with great explosion power that results come from sudden release of energy in fission reactions of heavy nuclei (uranium,plutonium ).
• Process of combining two lighter nuclei to give a heavier nucleus is called nuclear fusion.
• Process of splitting of nuclei of heavier atoms into two nuclei of comparable masses is called nuclear fission.
• Thus, A - 5 ; B - 3,4 ; C - 1 ; D - 2
