  title: Periodic Table First 30 Elements
  description: Atomic data for the first thirty chemical elements.
  summary: "The first thirty elements of the periodic table, from hydrogen to zinc, with atomic number, symbol, name and standard atomic mass. It covers the elements most common in introductory chemistry, biology and everyday materials."
  use_when[2]: "You need a symbol, name or atomic mass for the light elements.",You are checking an atomic number or building a small periodic-table lookup.
  caveats[2]: Only the first thirty elements are included; the table has 118.,Atomic masses are standard atomic weights rounded to four decimals and are averages over natural isotopes.
