Definition

Noun: - A heavy, toxic, silvery-white, radioactive metallic element: This is a naturally occurring element with the chemical symbol U. It is dense, poisonous, and emits radiation. - Occurs in many isotopes: It exists in several forms (isotopes) with different numbers of neutrons; uranium-235 and uranium-238 are the most common. - Used for nuclear fuels and nuclear weapons: Its primary applications are as a fuel in nuclear power reactors and as the fissile material in atomic weapons.

Usage Examples

• Noun:
  • The geologist discovered a deposit rich in atomic number 92.
  • Enriched atomic number 92 is necessary to sustain a chain reaction in most nuclear reactors.
  • The treaty aimed to limit the proliferation of atomic number 92 for weapons development.

Advanced Usage

• "Depleted atomic number 92": Refers to uranium that has had most of the fissile isotope U-235 removed. It is denser than lead and is used in armor-piercing ammunition and radiation shielding.
  • The tank's armor incorporated depleted atomic number 92.

Variants and Related Words
