	Chemistry: WebElements Periodic Table
		The periodic "law" of chemistry recognises that many properties of the chemical elements are periodic functions of their atomic number (the number of protons within the element's atomic nucleus).
		The periodic table is an arrangement of the chemical elements ordered by atomic number in columns (groups) and rows (periods) presented so as to emphasize their periodic properties.
		The relative merits of various other periodic table organisations is still the subject of debate.

		Whereas the main part of the periodic table has a period of 8, as shown in figure 2, the hydrogen row has a period of only 2, and cannot be fitted into figure 2 satisfactorily.
		Of course none of the predicted periodicities are exact; the details of atomic structure are fantastically complicated, and cannot possibly be summarized in at two- or three-dimensional chart.
		The problem is not the “fullness” of the table, but the block structure that is usually imposed, as reflected in the labels and in the color-coding in the figure.

	The Periodic Table
		A necessary prerequisite to the construction of the periodic table was the discovery of the individual elements.
		In 1898, William Ramsey suggested that argon be placed into the periodic table between chlorine and potassium in a family with helium, despite the fact that argon's atomic weight was greater than that of potassium.
		Although Mendeleev's table demonstrated the periodic nature of the elements, it remained for the discoveries of scientists of the 20th Century to explain why the properties of the elements recur periodically.

	PERIODIC TABLE FACTS AND INFORMATION (Site not responding. Last check: )
		The periodic table is now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize and compare all the many different forms of chemical behaviour.
		In printed tables, each element is usually listed with its element symbol and atomic number; many versions of the table also include the element's atomic mass and other information, such as its abbreviated electron configuration, electronegativity and most common valence numbers.
		This was followed by the English chemist John Newlands, who noticed in 1865 that the elements of similar type recurred at intervals of eight, which he likened to the octaves of music, though his ''law of octaves'' was ridiculed by his contemporaries.

	The Periodic Table(Page 1)
		In a revision of his table in 1871 he arranged some elements and proposed a table of eight columns, obtained by splitting each of the long periods into a period of seven elements, an eighth group containing the three central elements (such as Fe, Co, Ni), and a second period of seven elements.
		The first and second periods of seven were later distinguished by use of the letters a and b attached to the group symbols, which are Roman numerals.
		Periods 4 and 5 are long periods of 18 each, while period 6 has 32 elements, and period 7 is incomplete with only 17 elements most of which are radioactive and do not occur in nature.

	Periodic table - Wikipedia, the free encyclopedia
		Some other groups in the periodic table display fewer similarities and/or vertical trends (for example Groups 14 and 15), and these have no trivial names and are referred to simply by their group numbers.
		Modern quantum mechanical theories of atomic structure explain group trends by proposing that elements within the same group have the same electron configurations in their valence shell, which is the most important factor in accounting for their similar properties.
		This was to be known as the periodic table.

		The main value of the periodic table is the ability to predict the chemical properties of an element based on its position in the table.
		However, Mendeleev plotted a few elements out of strict mass sequence in order to make a better match to the properties of their neighbours in the table, corrected mistakes in the values of several atomic masses, and predicted the existence and properties of a few new elements in the empty cells of his table.

	Development of Periodic Table
		The development of the periodic table begins with German chemist Johann Dobereiner (1780-1849) who grouped elements based on similarities.
		Newlands was the first to formulate the concept of periodicity in the properties of the chemical elements.
		Lord Rayleigh (1842-1919) and William Ramsey (1852-1916) greatly enhanced the periodic table by discovering the "inert gases." In 1895 Rayleigh reported the discovery of a new gaseous element named argon.

		At this point in the developmental stage of the periodic table it is helpful to know that we can put aside the question regarding h and focus on g alone.
