when the elements mg and cl form an ionic bond, mg loses electron(s) from the 3s orbital to form the mg2 cation. cl gains electron(s) in the 3p orbital to form the cl– anion. since the total number of electrons lost always equals the total number of electrons gained, the compound formed will contain mg2 ions) for every cl– ion(s). fill in the blanks with the appropriate numbers.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
