atomic number 28

A scientist points to the atomic number 28 on a large periodic table chart.

Definition

Noun: 1. A chemical element: A hard, malleable, ductile, silvery-white metallic element that is resistant to corrosion. It is used in alloys and occurs in minerals such as pentlandite, smaltite, garnierite, and millerite. This element has the atomic number 28, meaning its atoms contain 28 protons in their nucleus.

Usage Examples
  • Noun:
    • The coin is made from an alloy containing atomic number 28.
    • Stainless steel often contains atomic number 28 to enhance its corrosion resistance.
    • The mineral garnierite is a primary ore for atomic number 28.
Advanced Usage
  • Scientific and Industrial Context: The term "atomic number 28" is primarily used in formal scientific, technical, and industrial writing to specify the element unambiguously by its fundamental property (proton count), especially in contexts discussing periodic trends, nuclear chemistry, or material specifications.
    • The catalyst required a metal with atomic number 28.
    • Alloys were tested based on the inclusion of elements like atomic number 26, atomic number 28, and atomic number 24.
Variants and Related Words
  • Nickel (Ni): This is the common name for the element with atomic number 28. "Atomic number 28" and "nickel" refer to the same chemical element.
    • The common name for atomic number 28 is nickel.
Synonyms
  • Nickel (Ni): The standard name for the element.
  • Element 28: An alternative systematic name based on its atomic number.
  • Metallic element: A general category to which it belongs.
Related Phrases and Contexts
  • Transition Metal: Atomic number 28 (nickel) is classified as a transition metal in the periodic table.
  • Ferromagnetic Element: It is one of the few elements that are ferromagnetic at room temperature.
  • Alloying Agent: A key use of atomic number 28 is as a component in alloys like stainless steel, cupronickel, and nickel-based superalloys.
