Definition

Noun: * A chemical element: A highly radioactive, dense, silvery-white metallic element found in very small quantities in uranium ores. It is an alkaline earth metal and its most stable isotope has a half-life of about 1600 years.

Usage

• Scientific Context: The term "atomic number 88" is used almost exclusively in scientific, technical, and educational contexts to refer to the element with 88 protons in its nucleus. Its common name is radium.
  • The periodic table lists radium with the symbol 'Ra' and atomic number 88.
  • Marie Curie discovered the element with atomic number 88.

Advanced Usage

• Specification in Nuclear Physics: Used to precisely identify the element in nuclear equations or when discussing isotopes, distinguishing it from other elements.
  • The decay chain involves an atom emitting an alpha particle and transforming into an atom with atomic number 86.

Variants and Related Words

• Radium (Ra): The common name for the element with atomic number 88.
• Alkaline earth metal: The group in the periodic table to which atomic number 88 (radium) belongs.

Synonyms

• Radium
• Ra (chemical symbol)

Notes

• The phrase "atomic number 88" functions as a systematic identifier. In most non-technical writing, the name "radium" is preferred. The "atomic number" designation is crucial for unambiguous communication in chemistry and physics.
