A survey of more than 12,000 teens found that the more love teens felt from their parents, the less likely they were to act in unhealthy ways having early sex, smoking, abusing drugs, and displaying alcohol violence. What are the three possible ways to explain this discovery? b) What characteristics of the experiment make it possible to isolate cause and effect?

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
