any of the elements in Group 18 of the periodic table, including helium, neon, argon, krypton, xenon, and radon, characterized by their inert nature and stable electron configurations

Ex: The noble gas configuration is characterized by a full outer electron shell , contributing to the stability and lack of reactivity .

emulsion

[noun]

a mixture of two liquids where tiny droplets of one are evenly dispersed in the other, like oil in water

Ex: Butter is an emulsion of water in fat , formed through the churning of cream , breaking down fat globules and dispersing them in the water phase .

half-life

[noun]

the time required for half of a quantity of a substance to undergo a change or decay, typically in the context of radioactive decay or chemical reactions

Ex: The concept of half-life is applicable in fields such as pharmacology , geology , physics , and environmental science .

radioactivity

[noun]

the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei in radioactive substances

Ex: Neutrons produced in nuclear reactions can induce radioactivity in materials through neutron activation .

depleted uranium

[noun]

a type of uranium that has most of its more radioactive isotopes removed, primarily used for armor-piercing ammunition and shielding

Ex: Depleted uranium can pose hazards if it enters the environment , such as through the release of dust or the contamination of soil and water .
