As the given element is sonorous and highly ductile, therefore, it is categorised as a metal. Some other expected characteristics are:
(i) It should possess metallic lustre.
(ii) It should be good conductors of heat and electricity.
(iii) It should be ductile.
(iv) It should be malleable.
(v) It should have high tensile strength.
(vi) It should have high densities and melting point/boiling point too.
(vii) It should be hard (except sodium and potassium which are soft metals).
(viii) It should be solid at room temperature (except mercury, which is liquid at room temperature).
While the characteristics of non-metals are:
(i) Non-metals are neither malleable nor ductile and do not conduct electricity.
Metalloids show some properties of metals and some other properties of non-metals.
