Krypton is a noble gas found in the Earth's atmosphere, known for its use in lighting and photography due to its bright white light when electrified. It is chemically inert, making it safe for various applications, but its rarity and extraction difficulty contribute to its high cost.

Noble gases are a group of inert, non-reactive elements found in Group 18 of the periodic table, known for their full valence electron shells that make them extremely stable. They include helium, neon, argon, krypton, xenon, and radon, and have significant applications in lighting, welding, and as inert environments for chemical reactions.

Earth's atmosphere is a complex layer of gases surrounding the planet, essential for supporting life by providing oxygen, protecting against harmful solar radiation, and regulating temperature. It consists of multiple layers, each with distinct characteristics and roles, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Lighting is the deliberate use of light to achieve practical or aesthetic effects, influencing mood, visibility, and perception of space. It encompasses various sources, techniques, and technologies to enhance functionality and ambiance in environments ranging from residential to commercial and theatrical settings.

Photography is the art and science of capturing images using light-sensitive materials or digital sensors, which can be used for artistic, documentary, or commercial purposes. It involves technical skills in camera operation and composition as well as an understanding of lighting, exposure, and post-processing techniques to create impactful visuals.

Rarity refers to the uncommonness or infrequency of an item, trait, or phenomenon, which often enhances its value or desirability in various contexts such as economics, biology, and culture. Understanding rarity involves assessing factors like distribution, demand, and intrinsic qualities that contribute to its scarcity and perceived worth.
