Question

“Electron” is an alloy of:
A. ${\text{Mg and Zn}}$
B. ${\text{Fe and Mg}}$
C. ${\text{Ni and Zn}}$
D. ${\text{Al and Zn}}$

Answer 1

Alloys are basically made up from the mixing of elements and at least one metal should be involved in the formation of alloys and that metal is known as base metal after which the alloy is given its name. Electron is an alloy made up from the mixing of two metals.

Complete step by step answer:
Alloy is a combination of metals or combination of metals with other elements. The alloys are made to get better properties which are better than the core elements or metals. The alloy contains all the properties of its parent materials and some new properties are introduced to it as per requirements.
Alloys have properties like electrical conductivity, luster, ductility, opaqueness and many more depending on the metals which we are mixing to make an alloy. The alloys have high
Some of the examples of alloy are:
Elemental iron is combined with carbon or silicon to produce steel which has properties like stiffness, toughness and high strength
Alloys are made by mixing two or more metals but one of them must be metal which is also termed as base metal, and sometimes the name of alloy is given on the name of base metal. We can see deviation in the mechanical properties of alloys, if we add two soft metals like copper and aluminium then their alloy which is known as aluminium alloy will have high strength and it will be more hard than copper and aluminium.
Electron is also an alloy, it is one of the magnesium alloys because the base metal used in the formation of Electron is magnesium. Electron alloy is used in making aircrafts. Electron is made up of $95\% Mg$ and $5\% Zn$ .

So, the correct answer is Option A .

Note:
Electron alloy is used in aircraft industries. It is very light, durable and has high strength. The reason behind the light weight Electron alloy is its specific gravity. The specific gravity of this alloy is less than that of aluminium and steel.
