Give an example of a metal which: Is a liquid at room temperature

Name a metal that burns in air?

Why is the reduction of a metal oxide if the metal formed is in liquid state at the temperature of reduction?

(A) The reduction of metal oxide is easier if the metal is in liquid state at temp of reduction (R) Delta S is -ve and Delta G is + ve

(A) Reduction of a metal oxide is easier if the metal formed is in liquid state at the temperature of reduction . (R) Delta G^(@) for the net reaction, reduction of metal oxide with the reductant, is more-ve when the metal formed is in molten state

Name few metals which occur in native state in nature. Why do they occur so?

Name one non-metal which is quite hard.
