Silver is used in film media because it tarnishes better than other materials.
Tarnish is the process of oxidation, where a metal turns from some some shiny color to a darker non-shiny color.
Three Examples of Tarnish:
Silver provides the best tonal range, from light to dark. It can capture light from pure white to pure black (or very close).
Additionally, silver tarnishes very consistently. This provides a smooth transition from light to dark on film.
Simple answer-it reacts with actinic ("white") light to make images.It can be carried on paper or film in a gelatine base layer.
Silver bromide, a silver halide, is a light-sensitive compound used in film emulsion. Other silver halides used in film include silver chloride and silver iodide.
Film emulsion contains silver halides: silver bromide (AgBr), silver chloride (AgCl) or silver iodide (AgI).
Silver Halide - because it does.
it is silver
Iodine ******** And silver.

A silver-lined umbrella is used to diffuse light from a flash that is pointed into the umbrella and therefore illuminates the subject with light from a large surface (the silver lining).
In jewelry and photography, several metals are commonly used for different purposes: Gold: Gold is a popular metal in both jewelry and photography. In jewelry, gold is valued for its beauty, malleability, and resistance to tarnish. It is available in various colors, including yellow, white, rose, and even green. In photography, gold is used in gold-plated reflectors to provide warm and flattering light to subjects. Silver: Silver is another commonly used metal in jewelry and photography. In jewelry, silver is known for its affordability, versatility, and classic appearance. It can be used in various styles, from modern to vintage. In photography, silver plays a historical role in traditional film photography, where light-sensitive silver halide crystals capture images on film. Platinum: Platinum is a precious metal highly valued in jewelry for its rarity, durability, and white luster. It is often used in high-end and luxury jewelry pieces. In photography, platinum prints were used historically for creating high-quality black and white images, though the process is less common today. Copper: Copper is sometimes used in jewelry for its unique reddish-brown color and malleability. It is often used as an alloy with gold to create rose gold. In photography, copper can be used as a base for printed circuit boards in cameras and other electronic equipment. Titanium: Titanium is a lightweight and strong metal commonly used in contemporary jewelry designs. It is hypoallergenic and often used for wedding bands and other jewelry pieces. In photography, titanium is used in the construction of camera bodies due to its durability and lightness. Brass: Brass is an alloy of copper and zinc, and it is used in jewelry for its golden appearance and affordability. It is often used in fashion jewelry and costume jewelry. In photography, brass is used in some vintage cameras and lens mounts. Aluminum: Aluminum is a lightweight and corrosion-resistant metal used in some contemporary jewelry designs, especially for statement pieces and modern styles. In photography, aluminum is used for making lightweight camera parts and accessories. Stainless Steel: Stainless steel is a durable and affordable metal used in contemporary jewelry, especially for men's jewelry and fashion pieces. In photography, stainless steel is used for various camera components and tripods. Each metal brings its unique properties and characteristics, allowing for a diverse range of designs and applications in both jewelry and photography.
Yes - silver does react and that is why there are quite a few compounds of silver. It is used in photography for example.

Iodine ******** And silver.
Silver halides absorb light to form elemental silver. This is the basis for the photographic film. This is an unusual reaction and is certainly not common to all ionic compounds. Silver halides are also unusually insoluble, again not a common property of ionic compounds. In fact silver halides have quite a lot of covalent character! I am sure teacher has something in mind but its certainly not in mine.
it is used in the compound silver iodide and it reflects the light. it is essentially the basis of black and white photography.
