valina [46]

Answer:

They have properties of both metals and nonmetals

Explanation:

  • Elements in the periodic table may be divided into Metals, non-metals, and metalloids.
  • Metals are the elements that react by losing electrons to form stable positively charged ions known as cations. Examples are group 1, 2, and 3 elements together with transition elements.
  • Non-metals are those elements that react by gaining electrons to form stable negatively charged ions called anions. Examples include oxygen, carbon, sulfur, etc.
  • Metalloids, on the other hand, are elements that have both metallic and non-metallic properties.
  • Metalloids occur between metals and non-metals in the periodic table. Examples include Boron and silicon among others.

Why are the gases in the troposphere layer denser than the gases in the other layers? Give reasons for your answer.
tiny-mole [99]
The troposphere has the most density because it has the most air pressure.  As you get higher in the atmosphere, the air gets thinner, which is why people who climb high mountains get sick because the air is not thick enough for them to breathe.
