Why does table salt dissolve in water and conduct electricity while sugar also dissolves in water but doesn't conduct electricity? Why does sugar have a low melting point while salt has a high melting point? Explain your
ideas about how differences in the chemistry of these substances explains their different properties.

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

just did the assignment and the answer was #1 +2 n

can you list the answers so i can answer

the right answer is c i just did the question.
