Complete the passage to describe projectile motion, using “horizontal” or “vertical.” when an object is thrown, the thrower pushes the object. this causes the object to move in a motion. inertia keeps the ball moving horizontally. the force of gravity acts on the object, causing motion. these two motions cause the motion of the object to curve downward.

Explanation: Hope this helps

In aluminium fluoride, aluminium carries positive charges so fluoride should carry negative charge to be electrically neutral.So for aluminium ion with three positive charges fluoride ion should possess three negative charges to make aluminium fluoride electrically neutral.
