Answer:
texture
Explanation:
Elements have been classified into three categories namely; metals, non-metals and metalloids. This classification was done based on certain characteristics or properties possessed by each element. Some of the characteristics used are: lustre, malleability, conductivity, melting point, boiling point etc.
- Metals are very good conductors of heat and electricity whereas metalloids and nonmetals are not.
- Metals and metalloids shine when polished i.e. they are lustrous, whereas nonmetals don't
- Metals are malleable i.e. can be beaten into sheets.
Texture is not a property used to classify metals and metalloids.
