These are silver halides as AgCl and AgBr.
Black light
Silver-based film stock turns black in a light negative, as it is developed using a chemical process that exposes the film to light and causes the silver halide crystals to darken where they have been exposed, creating the photographic image.
A balck bird is not an element. No living thing is an element.
Bromine
He is helium, a light, inert gas.
Neon (Ne) is a chemical element.
Light does not have a chemical symbol. Light is not a chemical element. It is not even a form of matter: it is energy Well but if it is used for condition it is represented by "hv"- [eight aphabet of english alphabet{h} and 13th letter of greek alphabet{v}called "nu"]
The color of the light emitted by an element heated within a flame is a physical characteristic, but this particular physical characteristic is itself determined by a chemical characteristic: the distribution of electron energy levels within the element.
It is chemical energy. it transform sun light to chemical energy.
Yes, black light can cure resin by initiating a chemical reaction that hardens the resin.
Black is just a "color" made by a surface chemical absorbing all light, therefore meaning that if there is no light, objects will look black.
The chemical compound in Lysol that causes it to fluoresce under a black light is specific to certain formulations of Lysol and is typically a fluorescent dye such as fluorescein. These dyes absorb UV light and emit visible light, making them appear to glow when exposed to a black light.
