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 it when

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.

Watch out for

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.

Fields

The shape of this dataset, read from the data itself: every column, its type and a real value. Agents can use this to plan a query without fetching the whole document.

Section	Field	Type	Example
data	`atomic_number`	integer	1
data	`symbol`	string	H
data	`name`	string	Hydrogen
data	`atomic_mass`	number	1.008

Fetch the same bytes

The static files contain the same reference rows as the API, with no API rate limit. Live metadata, such as view counts, may differ. Use the API for content negotiation; use the static files for a cacheable snapshot.

curl "https://yjtoon.yunusemrevurgun.com/api/dataset/periodic-table-first-30?format=toon"

const res = await fetch(
  "https://yjtoon.yunusemrevurgun.com/static-data/dataset/periodic-table-first-30.toon"
);
const toon = await res.text();
