...the branch of natural science that studies the synthesis, analysis, elucidation of the structure and properties of the substances that make up the things around us, ourselves, the Earth we live on, and the universe that extends beyond the Earth, as well as the reactions between substances. Chemistry deals with both simple substances and compounds, but in both cases, it often deals with substances that have a relatively uniform composition. Because the subject matter is extremely broad, it is convenient to think of chemistry as being divided into several fields. The most common classification is into five fields based on the subjects and methods of chemistry: physical chemistry, organic chemistry, inorganic chemistry, biochemistry, and applied chemistry.

From the Periodic Table

The periodic table is a table showing the physical and chemical properties of elements, which change periodically as their atomic number increases.
[The history of the discovery of the periodic table]
At the end of the 18th century, when the concepts of modern chemistry were just beginning to take hold, chemists had a fairly incomplete knowledge of about 30 elements. But new elements were discovered one after another, and by the 1860s there was a fairly extensive and accurate knowledge of the properties of about 60 elements, especially their atomic weights.

Japanese:

…われわれの身のまわりのもの,われわれ自身,われわれの住みかである地球,その地球の外に広がる宇宙,これらを構成する物質の,合成,分析,構造や性質の解明,さらには物質相互の間の反応を研究する自然科学の一部門。化学では単体も化合物も扱うが,どちらの場合も比較的単一な組成をもつ物質を扱う場合が多い。その対象がきわめて広範なので,化学をいくつかの分野に分けて考えるのが便利である。最も一般的な分類は,物理化学,有機化学,無機化学,生物化学,応用化学の対象・方法別の5分野への分類である。…

【周期律】より

…元素の物理・化学的性質は,その原子番号の増加とともに周期的な変化をくりかえしていくという化学の根本的な法則。これを表の形で表したものが周期表である。
[周期律発見の歩み]
 18世紀の末,近代化学の諸概念がようやく確立しかけてきたころには,化学者は約30ばかりの元素について,かなり不完全な知見をもつにすぎなかった。しかしその後新しい元素がつぎつぎに発見され,1860年代には約60の元素の諸性質,なかんずくそれらの原子量について,相当に豊富,正確な知識が得られるようになった。…
