Not all elements readily fit in the metal or non metal groupings. These elements are called metalloids. Examine the table below and classify W, X and Y as metals, metalloids or non-metals. W= Lustre: Moderately high
Electrical conductivity: Low
Density: Medium
Melting point: Very high

X= Lustre: Low
Electrical conductivity: Nil
Density: Low
Melting point: Low

Y= Lustre: High
Electrical conductivity: High
Density: High
Melting point: High
