This would be more of a chemistry question. Remember magnesium has a charge of 2+, and would need to hand off its two extra electrons. Fluorine can only take one electron at a time, so there needs to be two fluorines to take one magnesium's 2 electrons.
With lithium, it has a +1 charge, so it has one extra electron, which it can hand off to just 1 fluorine atom.
Another way of looking at this is:
+ 2
= MgF2 (the charges must balance out to zero)
+ = LiF (the charges balance out to zero)
With lithium, it has a +1 charge, so it has one extra electron, which it can hand off to just 1 fluorine atom.

Answer:
The horizontal distance covered by the firework will be
Explanation:
Let acceleration due to gravity on the planet be g, initial velocity of the firework be u and angle made with the horizontal be ∅.
writing equation of motion in vertical direction:
and
therefore
writing equation of motion in horizontal direction:
therefore the equation becomes
therefore horizontal distance traveled =
