Question

An element is sonorous and highly ductile. Under which category would you classify this element? What other characteristics do you expect the element to possess?

Answer 1

Metals are sonorous as make a melodious sound and can be drawn into wires and are therefore ductile. So, the element is a metal.

Physical characteristics of the element (metal) are :
1. The elements possess a shiny surface or metallic lustre.
2. It can be easily drawn into thin sheets i.e. it is malleable.
3. It is a good conductor of heat and electricity.

Chemical properties of the element are:
1. It reacts with dilute acids to form the corresponding salt and release hydrogen gas, H₂.
Metal or element + dilute acid $\to$ salt + hydrogen gas
2. It can displace less reactive metals than itself from their salt solutions.
Metal or element + Metal salt of B $\to$ salt of element + metal B
