Answer:
Radon
Explanation:
One element that will have similar property as an atom with 118 protons is Radon because it will belong to the p-block and the noble gas group.
The element will follow atomic number 117 which is already in the 7th group on the periodic table.
- Generally, on the periodic table, elements in the same group will have the same chemical property.
- The valency of most elements determines their chemical behavior.
- Since our mystery element is in the 8th group, noble gas group, it will mostly behave like any of the elements in the group.
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.
