Explain how are precipitation and temperature between the polar and the tropical climate zones?

There are regions with tropical climate that have large temperature variations between summer and winter and these variations could be as high as 25-30 degree Celsius. Polar climate zone is characterized by extremely low temperatures throughout the year.

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
