Question

Electron is an alloy of magnesium along with:
A) Barium
B) Sulphur
C) Tin
D) Aluminium

Answer 1

Hint: It is a factual type question about the composition of the alloy. Alloys are those substances or metals formed by the combination of two or more other metals.

Complete answer:
The question asked is completely a fact based question and to answer the above question we should know the composition of the alloy elektron.
So let’s discuss some facts, the composition and the uses of the alloy elektron.
Electron is the common name or can be said as the trademark name for the magnesium alloys. The major composition in the alloy is the magnesium metal and electron was manufactured by a British company called Magnesium Elektron Limited.
The Magnesium alloys prepared by the company consists of 100 of alloys in which the other metals have a concentration of about 0-9.5%.
The elektron alloy which was produced in the initial stage has a composition of various metals of about-Magnesium (90%), Aluminium (9%) and other (1%).
So we can simply say that the elektron alloy is an alloy of the metals Magnesium and Aluminium.

So the correct answer for the question from the above options is option (D).

Additional Information:
By adding various metals in various concentrations to make the Mg alloy, it results in the altering the mechanical properties of the alloys formed.
And the alloys formed have high tensile strength, thermal stability, are resistant toward corrosion and are creep resistant and are lighter than other alloys.
Because of these properties, they find application in the aerospace engineering field, automobile pistons, motor racing applications etc.

Note:
There is a chance of getting confused with electrum, which is also an alloy. Electrum is a naturally occurring alloy of gold and silver with some traces of copper in them. Earlier this alloy was called as the white gold and its colour ranges from pale to bright yellow. It is now produced artificially also and is called as the green gold.
