How is graphite structured? A. Each carbon is bonded to four others making it very solid and rigid. B. Its carbon atoms are bonded to 3 other carbon atoms and are structured in layers that can slip past each other. C. Its carbon atoms are bonded to 3 other carbon atoms and are structured in layers that cannot slip past each other. D. Each carbon atom is surrounded entirely by lone pairs, which is why the carbon atoms separate from each other to the paper easily when writing.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

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

the answer is minerals.
