Lithium in column 1 of the periodic chart is in a column which forms +1 ions: Li+1
nitrogen is located 3 columns to the left of the noble gas column, a position that makes -3 ions
Nitride is N-3
lithium nitride is made with Li+1 & N-3
since compounds have an equal amount of positiveness & negativeness
we need 3 positives to balance with nitride's -3
that comes with 3 Lithiums: Li+1 ,& Li+1 & Li+1
your answer is
Li3N
