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.
