It is 100 years in the future and several new elements have been discovered,
including Jollium (symbol Jo). This element has been found to combine with nitrogen
to make a brand new polyatomic ion named Jollinate with the chemical formula
$JoN_4$.
If lithium jollinate has a chemical formula of $Li_3JoN_4$, what is the charge on the
jollinate ion? You MUST EXPLAIN your reasoning for how you determined the
charge. [no explanation, no points]
