An element X has the following properties
It is ductile
It conducts heat well
It forms ionic chlorides
It has variable oxidation state
It reacts with oxygen
It forms colored ions
It displaces hydrogen from dilute hydrochloric acid. Which of the following properties indicates that X is a metal?
The properties that indicate that X is a metal are:
- It is ductile
- It conducts heat well
- It has variable oxidation state
- It reacts with oxygen
- It displaces hydrogen from dilute hydrochloric acid.
These properties are typical of metals, which are malleable, good conductors of heat and electricity, have variable oxidation states, react with oxygen to form oxides, and can displace hydrogen from acids.
The fact that X forms ionic chlorides and colored ions is also consistent with it being a metal, as many metals form ionic compounds with nonmetals and can produce colored ions due to the presence of d-orbitals in their electronic structure.
Therefore, based on these properties, it is likely that X is a metal.
