Question

_________ have properties intermediate between those of metals and nonmetals.

Answer 1

• Some of the elements have properties intermediate between metals and non-metals, these elements are called metalloids.
• Metalloids are a small group of elements founds in the periodic table of elements along the zigzag line that distinguishes metals from non-metals.
• Examples - boron ($\mathrm{B}$),silicon ($\mathrm{Si}$), germanium($\mathrm{Ge}$)

Therefore, metalloids have properties intermediate between those of metals and non-metals.
