These are the 118 currently known and officially
named elements that make up the periodic table
(IUPAC 2016). Each element is represented by an
image produced for the Visual Elements project.
Atomic number
The periodic table arranges the elements, with their
diverse physical and chemical properties, in order of
atomic number and fits them into a logical pattern.
Eighteen columns divide the elements into groups
with closely related physical properties. Rows list
elements in order of mass and are called series or
periods. Properties of elements change in a systematic
way through a period.
The ratio of the average mass of the
various isotopic forms of an element to
one-twelfth of the mass of a carbon-12
atom in its ground state. A number in
brackets indicates that all isotopes of the
element are unstable, ie radioactive.
Group 13
The atomic number is equal to the
number of protons in the nucleus.
