Answer 1

As the given element is sonorous and highly ductile, therefore, it is categorised as a metal. Some other e pected characteristics of are (i) It should possesses metallic lustre and can be polished. (ii) It should be good conductors of heat and electricity. (iii) It should be ductile. (iv) It should be malleable. (v) It should has high tensile strength. (vi) It should has 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. (ii) Metalloids show some properties of metals and some other properties of non-metals.

Hope it helps u mate

Answer 2

Answer:

An element which is metal can have :

(1)Ductility: can be drawn in wire. Exception = Sodium , Potassium, Malleability: Can be hammered, pressed, an make it thin sheets. Exception = Sodium , Potassium

(2)Lustre: Have bright, shining surface

(3)Tensile strength if metal is very high. Exception = Mercury

(4)Metals are hard and solid. Exception = Sodium , Potassium

(5)Metals are sonourous.

The element which are non - metal have opposite characteristics from metals.  

So the given element is a metal.  ANSWER
