Why copper is found and formed only in some parts of America

Copper is found in many parts of the world. It usually comes from copper ore, but small amounts are occasionally found ("native copper") in distorted cubic crystal chunks. Keweenaw Peninsula near Lake Superior in Michigan is one of the most likely places to find native copper!!

Explanation:

they both have a y in them

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
