For the nuclear reactions
(A) 8Be4 → 2 4He2
(B) 80Kr36 → 2 40Ar18
(Given masses: 8Be4 = 8.005300, 4He2 = 4.002603 and 80Kr36 = 79.81638, 40Ar18 = 39.96238)
The correct statement is:
(A) 8Be4 → 2 4He2
(B) 80Kr36 → 2 40Ar18
(Given masses: 8Be4 = 8.005300, 4He2 = 4.002603 and 80Kr36 = 79.81638, 40Ar18 = 39.96238)
The correct statement is:
- a)(A) and (B) are both spontaneous fission processes
- b)(A) is spontaneous fission but (B) is not
- c)(B) is spontaneous fission but (A) is not
- d)Both (A) and (B) are not spontaneous fission processes
Correct answer is option 'B'. Can you explain this answer?

The binding energy of reaction A
- BE=(8.005206-8.005300) x (3x108 m/s)2
- BE=(-0.000094) x (3x108 m/s)2
- BE= -28200J (energy is released)
- This tells that reaction A is spontaneous.
The binding energy of reaction B
- BE=(79.92476-79.81638) x (3x108 m/s)2
- BE=(0.10838) x (3x108 m/s)2
- BE= 3251400J (energy is required)
- This tells that reaction B is non-spontaneous.
So, (A) is spontaneous fission but (B) is not

The nuclear reaction you have mentioned is the alpha decay of beryllium-8, which is commonly written as:
(8)Be -> (4)He + (4)He
In this reaction, an atom of beryllium-8 (with a mass number of 8 and an atomic number of 4) undergoes alpha decay, resulting in the formation of two helium-4 nuclei. An alpha particle, which is essentially a helium-4 nucleus, is emitted from the beryllium-8 nucleus.
This reaction is a common example of alpha decay, where a heavy nucleus emits an alpha particle to become more stable.
(8)Be -> (4)He + (4)He
In this reaction, an atom of beryllium-8 (with a mass number of 8 and an atomic number of 4) undergoes alpha decay, resulting in the formation of two helium-4 nuclei. An alpha particle, which is essentially a helium-4 nucleus, is emitted from the beryllium-8 nucleus.
This reaction is a common example of alpha decay, where a heavy nucleus emits an alpha particle to become more stable.
