SŁOWNICTWO Z OBSZARU: Chemia - Chemistry

Chemistry, from Greek language

χυµεία

means "study of liquids", is a branch of

science. Modern chemistry focuses on the study of elements of the world and the
bonds between elements. Chemistry also deals with composition, structure, and
properties of substances and the transformations they undergo. Chemistry also
investigates its interactions with energy and itself. Chemists often study how atoms
of different chemical elements interact to form molecules, and how molecules
interact with each other.

A chemical element is a type of atom that is distinguished by its atomic number;
that is, by the number of protons in its nucleus. The term is also used to refer to a
pure chemical substance composed of atoms with the same number of protons.
Common examples of elements are iron, copper, silver, gold, hydrogen, carbon,
nitrogen and oxygen. In total, 117 elements have been observed as of 2008, of
which 92 occur naturally on Earth. All chemical matter consists of these elements.
New elements of higher atomic number are discovered from time to time, as products
of artificial nuclear reactions.
