PERIODIC TABLE OF THE ELEMENTS

Hydrogen

Dmitri Mendeleyev (1834 -1907)

The Russian Chemist, Dmitri Mendeleyev, was the first to observe that if elements

were listed in order of atomic mass, they showed regular (periodical) repeating properties.

He formulated his discovery in a periodic table of elements, now regarded as the

backbone of modern chemistry.

The crowning achievement of Mendeleyev’s periodic table lay in his prophecy of then,

undiscovered elements. In 1869, the year he published his periodic classification, the

Lithium

element gallium, germanium and scandium were unknown. Mendeleyev left spaces for

Beryllium

them in his table and even predicted their atomic masses and other chemical properties.

Six years later, gallium was discovered and his predictions were found to be accurate.

Other discoveries followed and their chemical behaviour matched that predicted by

Mendeleyev.

The remarkable man, the youngest in a family of 17 children, has left the scientific

community with a classification system so powerful that it became the cornerstone in

Magnesium

chemistry teaching and the predication of new elements ever since.

Sodium

In 1955, element 101 was named after him: Md - Mendelevium.

In this remarkable chart, originally prepared by the South African Agency for Science

& Technology Advancement (SASTA) the elements are shown with an item of daily

use. The symbols, names and atomic numbers of the elements are given.
