atomic number 98
Definition
Noun: - A radioactive transuranic element: A synthetic, heavy metallic element with the symbol Cf and atomic number 98, produced artificially by bombarding curium with alpha particles. It is part of the actinide series.
Usage
- As a subject or object in a sentence: The term "atomic number 98" is used in scientific contexts to specifically identify the element californium by its fundamental property—the number of protons in its nucleus.
- The synthesis of atomic number 98 was a significant achievement in nuclear chemistry.
- Scientists needed a sample containing atomic number 98 for their experiment.
Advanced Usage
- In technical nomenclature: Used to unambiguously refer to the element californium, especially in formulas, tables, or when discussing periodic trends.
- Elements up to atomic number 98 can be produced in nuclear reactors.
- Distinguishing isotopes: While "atomic number 98" defines the element, it is often discussed alongside mass numbers to specify isotopes.
- The most stable isotope of atomic number 98 has a mass number of 251.
Variants and Related Words
- Californium (Cf): The common name for the element with atomic number 98.
- Californium-252 is a neutron-emitting isotope used in various applications.
