Lv(Livermorium) =Group 7,Period 7
O(Oxygen)=Group 7,Period 2
Oxygen is in group 6 actually. Therefore, it needs to gain 2 electrons to have a full outer shell. (2- ion).
Livermorium also apperars to be in group 6, and the same principles apply.
So the compound LivermoriumOxide is...
Lv(small 2)O(small 2)
Although i’ve never heard of that compound in my life. 😂
