What statement is true about the eight elements on the periodic table termed metalloids?
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.
