Why do ions in an ionic compound typically form an orderly crystal structure? a. All ionic compounds form solid crystals at room temperature.

b. Every ion is attracted to ions of opposite charge that surround it—above, below, and to all sides.

c. When crystals of ionic compounds are melted, the ions are able to conduct an electric current.

d. Some ions in an ionic compound have negative charges and some have positive charges

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
