2. ʳᵉᵃᶜᵗⁱᵛⁱᵗʸ ˢᵉʳⁱᵉˢ ᵒᶠ ᵐᵉᵗᵃˡˢ ​

Answer 1

Answer:

Alloy are made for the following reasons:-

1. To make them high resistance to corrosion

2.Make them strong And harder

Reactivity series is a series of elements arranged on the basis of their reactivity in assessing order

The series are

1.Potassium

2.Sodium

3.Calcium

4.Magnesium

5.Aluminium

6.Carbon

7.zinc

8.iron

9.tin

10.lead

11.hydrogen

12.copper

13.silver

14.gold

15.platinum

Here, potassium is the most reactive metal and platinum is the least reactive metal

Thank you
