HISTORY OF PERIODIC TABLE
1. From the time of the ancient Greeks up to 1700, only 14 elements were
known. Then, in a short span of ten years, 1800 to 1810, 14 more elements
were discovered. By 1830, 45 elements were known.
2. Chemistry had come a long way from the days of the Greeks, who thought
that only four elements existed. But as new elements were discovered,
chemists probably began to feel insecure. All these elements had different
properties, and there didn´t seem to be any relationship among them. And
chemists wondered how many elements actually existed. To answer this
question, they had to find some relationship among the known elements.
3. The first chemist to notice some order among the elements was the German
scientist Johann Dobereiner. He published an account of his observations
in 1829. It occurred to Dobereiner that bromine had chemical and physical
properties somewhere between those of chlorine and iodine, and that
bromine´s atomic weight was almost midway between those chlorine and
iodine. Could this be coincidence, or was there really some order to the
elements?
4. Dobereiner found two more groups of similar elements: the first was calcium
(Ca), strontium (Sr) and barium (Ba); the second was sulfur (S), selenium
(Se), and tellurium (Te). He called these groups triads (threes).
5. In 1864 the English chemist John Newlands tried to arrange all the known
elements in order of increasing atomic weight. He hit on the idea of
arranging them in vertical columns. Since he noticed that the eighth
element (sodium) had chemical and physical properties called his
arrangement the Law of Octaves. But there were many places in his
arrangement where dissimilar elements were next to each other.
6. In 1869 the Russian chemist Dmitri Mendeleev arranged the elements so
that their order depended on the similarity of their chemical properties.
Mendeleev established horizontal rows, or periods. Hydrogen by itself
made up the first period. The next two periods each contained seven
elements. The periods after that contained more than seven elements. This
is the point at which Mendeleev´s table differed from Newlands´ table.
7. In arranging his table, Mendeleev occasionally put heavier elements before
lighter ones in order to keep elements with the same chemical properties in
the same vertical column (group). Sometimes he left open spaces in the
table, where he reasoned that unknown elements would go. This was the
case with gallium. In 1869, when he made up his table, the element gallium
was unknown; however, Mendeleev predicted its existence. He based his
theory on the properties of aluminum (which appeared directly above
gallium on the table). Mendeleev even went so far as to predict the melting
point, boiling point, and atomic weight of the then-unknown gallium, which
he called eka-aluminum. Then, six year later, while analyzing zinc ore, the
French chemist Lecoq de Boisbaudran discovered the element gallium. Its
properties were identical to those Mendeleev had predicted six years carlier.
8. The periodic table of today is similar to Mendeleev´s; however, many new
elements have been discovered since 1869. Today´s table consists of
seven horizontal rows called periods and a number of vertical columns
called groups (or families). The groups are numbered with roman numerals.
Because they have the same numbers of electrons in their outer shells,
elements in a particular group behave in similar ways.
9. You´ll notice that in the periodic table some of the groups are labeled with a
roman numeral followed by A, others with a roman numeral followed by B.
The A groups are called the representative elements. The B groups are
called the transition metals. You can also see that, as we move from the top
to the bottom of the periodic table (in other words, from period 1 to period 7),
the periods get larger; they have more elements in them. In fact, periods 6
and 7 are so large (32 elements in each) that to fit the table on one page,
we have to write part of each period bellow the rest of the table (the 15
lanthanides and 15 actinides).
