Answer 1

1⃣.Pure metals possess few important physical and metallic properties, such as melting point, boiling point, density, specific gravity, high malleability, ductility, and heat and electrical conductivity. ... Alloys are made to: Enhance the hardness of a metal: An alloy is harder than its components.

2⃣.Reactivity Series in chemistry is an experimental, structural and logical progression of series of metals in order of reactivity from highest to lowest. Metals react differently with different substances. It gives a descriptive detail on metal reactions with the extraction of metals from ores and with acids and water.

Answer 2

1. Purpose of Making Alloys. Enhance the hardness of a metal: An alloy is harder than its components. Pure metals are generally soft. The hardness of a metal can be enhanced by alloying it with another metal or nonmetal.
2. Reactivity Series of Metals. Reactivity Series in chemistry is an experimental, structural and logical progression of series of metals in order of reactivity from highest to lowest. Metals react differently with different substances. All metals have a tendency to lose electrons and form metal ions.
