Electric charges surround you all the time. Some electric charges, such a lightning, are quite strong. Others are barely
noticeable. What happens when two electrically charged
objects get near each other? Cide the response that best
matches your thinking.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

b) nuclear ive learned that in a pedtrodic table

the objects have the same charge.
