According to the periodic table, which statement correctly describes the change from a neutral atom of an element to its ion? A) A iodine atom forms a I- ion by losing one electron.
B) A calcium atom forms a Ca2+ ion by losing two electrons.
C) A cesium atom forms a Cs+ ion by gaining one electron.
D) A sulfur atom forms a S2- ion by gaining one electron.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
