- Al, Mg and Ni
- Al, Mg, Mn and Cu
- Al and Ni
The Correct Option is C
Solution and Explanation
Duraluminium alloy contains Al (95%), Cu (3%), Mn (1%), Mg (1%)
When two or more metals are combined, a substance known as an alloy is produced. Metals may also be created by combining them with other elements. On the other hand, alloys have qualities that are different from those of the individual attributes of these components. When compared to pure metals, alloys are harder and stronger. For instance, combining gold with copper creates red gold, an alloy. Another kind of alloy is white gold, which is a combination of silver and gold. Today, we'll examine the definition of an alloy, its components, and what an alloy is in terms of chemistry.
- A substance having metallic properties called an alloy is composed of two or more elements, at least one of which is a metal.
- A material has metallic properties if it appears shiny when it is first created, fractured, or polished.
- Additionally, it is a good heat and electrical conductor. The majority of metals are malleable, making it simple to hammer them into thin sheets.
- They may also be fashioned into wires since they are ductile.
- Chemical elements like iron or alloys like stainless steel are considered to be metals.
- For use in practical applications, most pure metals are either excessively soft, brittle, or chemically reactive.
- The original characteristics of metals are altered to provide desired features when different metal ratios are combined as alloys.
- Alloys are frequently created to be more resilient to corrosion, more durable, or to have a more pleasing lustre and hue.

Concepts Used:
P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
