Final answer:
Titanium is used for implants due to its biocompatibility and corrosion resistance. Silver is valued for its luster and electrical conductivity, making it ideal for jewelry, coins, and electronic components. Alloys like brass and bronze have unique properties making them suitable for musical instruments and casting, respectively.
Step-by-step explanation:
Metal implants in the human body are often made of titanium because it is strong, lightweight, and most importantly, it is biocompatible, meaning it is non-toxic and not rejected by the body. Titanium's resistance to corrosion also makes it ideal for long-term implantation in the human body.
Jewellery and coins are frequently made of silver due to its lustrous appearance and malleability, which allows it to be crafted into intricate designs. Silver also has antibacterial properties, making it beneficial for items in close contact with the skin.
Electrical and electronic components often utilize silver because it is the best conductor of electricity among all elements, which enhances performance by reducing energy loss and increasing efficiency in electrical conduction.
Alloys such as brass, made of zinc and copper, and bronze, made of copper and tin, have their own special applications due to their unique properties. Brass is highly malleable and has excellent acoustic properties for musical instruments, while bronze is harder than copper and well-suited for casting. Steel is widely used in construction due to its high tensile strength and durability. A substitutional alloy is a mix where the atoms of one element replace the atoms of another in a crystal lattice, which can result in enhanced material properties.
