Definition

Noun: A radioactive, synthetic, metallic chemical element with the symbol Am and atomic number 95. It is a member of the actinide series and is produced artificially by bombarding uranium or plutonium with neutrons.

Usage

The term "atomic number 95" is the formal, scientific designation for the element americium. It is used primarily in technical, chemical, and nuclear contexts to specify the element by its fundamental property (the number of protons in its nucleus) rather than its given name. - The periodic table lists americium at position atomic number 95. - The sample was confirmed to contain isotopes of atomic number 95.

Advanced Usage

• In nuclear physics and chemistry, the term is used to classify and discuss elements systematically, especially for those that are synthetic or highly radioactive.
  • The reactor's byproducts included elements up to atomic number 95.

Variants and Related Words

• Americium (Am): The common name for the element with atomic number 95.
• Transuranic element: A category of synthetic elements with atomic numbers greater than 92 (uranium), which includes atomic number 95.
• Actinide: The series of elements on the periodic table from atomic number 89 to 103, which includes atomic number 95.

Synonyms

• Americium (This is the direct synonym, being the element's name).
