Answer:

Hey Buddy!!!!

Alloys are made to: 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.

The reactivity series is a series of metals, in order of reactivity from highest to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series.

Hello mate!

☑ Purpose for making alloys :-

• An alloy is a combination of a metal and one or more other elements..
• It resists corrosion.
• Alloy is harder than pure metal
• The process of alloying improves the quality of metals.

☑ Reactivity series of metal :-

• The reactivity series is the arrangement of metals based on their increasing reactivity.
• The upper elements are most reactive followed by Potassium, sodium, lithium etc.
• The elements after hydrogen are least reactive...

Hope it helps ❤☺
