Question

The table below shows the physical properties and important uses for three elements on the periodic table.

Which option describing these elements is true?

A.
All three elements are rare-earths.
B.
The first and third elements are metals. The second element is a nonmetal.
C.
The first and third elements are rare-earths. The second element is a nonmetal.
D.
All three elements are nonmetals.

Answer 1

To accurately answer this question, I would need to see the table you are referring to. However, I can provide some information about rare-earth elements and the general classification of metals and nonmetals:

• Rare-earth elements are a group of 17 elements, including the 15 lanthanides and scandium and yttrium. They are typically metals.
• Metals are usually shiny, malleable, and good conductors of heat and electricity.
• Nonmetals are generally brittle, not shiny, and poor conductors. Examples include elements like carbon, nitrogen, and oxygen.

If you can provide the specific details about the three elements in the table, I can help determine which option is true.
