Answer: The correct option is, 2.
Explanation:
Nuclear fission: It is defined as the reactions in which a larger unstable nuclei breaks into two or more smaller stable nuclei.
Nuclear fusion: It is defined as the reaction where two smaller nuclei combine together to form a larger nuclei.
Option 1 & option 2 shows fusion reaction and option 3 & option 4 shows fission reaction.
In option 1, helium itself is forming but in option 2, element is heavier than forming which is, neon.
Hence, the correct option is 2.

Answer:
Explanation:
Hund's Rule of Maximum Multiplicity states that electrons go into degenerate orbitals of sub-orbitals(p, d and f) singly before pairing commences.
Hund's rule is useful in determining the number of unpaired electrons in an atom. Hence, it explains some of the magnetic properties of elements.
An element whose atoms or molecules contain unpaired electrons is paramagnetic.
The element whose atoms or molecules contain orbitals that are all filed up with paired electron is diamagnetic.
Answer:
i think that the answer would be 7 because 8 or less is for 1 shell so I think that it makes most sence
