Help a) Type several paragraphs describing your “core sample” of Earth’s layers in detail.
i. Explain what a core sample is. Then, tell whether it is currently possible to take a core
sample like the model you’ve created.
ii. Compare and contrast the layers in your model, including the significance of the
colors.
iii. Discuss what it means to create a scale model.
iv. Include a table with the values you determined for each layer.
v. Discuss the relationships of each layer to the others, including depth.

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
