What scientist published the first periodic table and how was it arranged?
In 1817, Döbereiner began to formulate one of the earliest attempts to classify the elements. He found that some elements formed groups of three with related properties. He termed these groups "triads". In all of the triads, the atomic weight of the second element was almost exactly the average of the atomic weights of the first and third element..
Who started the Actinide family?
From the earlier known chemical properties of Actinium (89) up to Uranium (92), indicating a relation to the transition metals, it was generally assumed that the transuraniums would have similar qualities. During his Manhattan Project research in 1944, Glenn T. Seaborg experienced unexpected difficulty isolating Americium (95) and Curium (96). He began wondering if these elements more properly belonged to a different series than the transition metals, which would explain why the expected chemical properties of the new elements were different. In 1945, he went against the advice of colleagues and proposed the most significant change to Mendeleev's periodic table to have been accepted universally by the scientific community: the actinide series.
How does the periodic table work-?
The layout of the periodic table demonstrates recurring ("periodic") chemical properties. Elements are listed in order of increasing atomic number (i.e. the number of protons in the atomic nucleus). Rows are arranged so that elements with similar properties fall into the same vertical columns ("groups"). According to quantum mechanical theories of electron configuration within atoms, each horizontal row ("period") in the table corresponded to the filling of a quantum shell of electrons. There are progressively longer periods further down the table, grouping the elements into s-, p-, d- and f-blocks to reflect their electron configuration. In printed tables, each element is usually listed with its element symbol and atomic number; many versions of the table also list the element's atomic mass and other information, such as its abbreviated electron configuration, electronegativity and most common valence numbers. Hope this helps.
How did the congress organize the sale of the western lands?
They didn't really organize it. After the French lots the French and Indian war and lost their land, the British just began to claim the Western lands for themsevles. Congress did not have an organization... I believe. God bless.
Did Maxwell create and early periodic table?
Maxwell is not a Russian scientist! It is the the brand name of an obsolete American automobile- popular with the comedian Jack Benny. Dimitri Mendeleev was the Russian scientist you seek. He died in l907. Mendeleev was a government scientist of the Imperial Bureau of Standards and as you stated he created the modern Periodic table of the elements- which is basic to the study of Chemistry. For some odd reason- maybe because he was a government scientist- he was never awarded the Nobel Prize in Chemistry despite being eligible as the prizes began in l900 and he lived until l907. One would think he was a Nobel candidate- with such a major contribution to chemistry- still in everyday use though new elements come up all the time!
What propertis of the elements did you list as you began to organize the elements Dmitri Mendeleev?
He "Dmitri" propose that the periodic table of elements that the elements should be grouped by rows and column and by atomic mass,

How did Dmitri Mendeleev arrange the elements in the periodic table?
Mendeleev ordered the elements from lowest atomic mass unit (amu) to highest atomic mass unit.
How did Mendeleev arrange the chemical elements in the periodic table?
Mendeleev arranged the elements by their relative atomic mass. Each one of his rows began with an element that had 1 valency and ended it with inert gas elements. The creator of the Periodic Table, Dimitri Mendeleev, arranged the elements by atomic number (amount of electrons) and amount of electron shells. This then lead to columns (groups) of elements with the same amount of electrons in their outer shell. So, now, every period contains elements with ascending atomic numbers. Every group contains elements with ascending amounts of electron shells.
First person to arrange elements in a table?
Dmitri MendeleevIn ancient Greece, Aristotle postulated that there were four elements (fire, water, earth, air) and arranged these accordingly. Later on when science began to theorize (and later prove) the existence of atomic elements without the benefit of knowing the subatomic properties involved, people sorted them in many different ways.In 1829 Döbereiner proposed the Law of Triads: The middle element in the triad had atomic weight that was the average of the other two members.The English chemist John Newlands, noticed in 1865 that when placed in order of increasing atomic weight, elements of similar physical and chemical properties recurred at intervals of eight, which he likened to the octaves of music. As knowledge about subatomic particles increased, this system proved unreliable and fell into disfavor.The modern periodic table of elements which is based on both atomic weights and chemical properties was developed by Dmitri Ivanovich Mendeleev in 1869. Four months later, a German professor Julius Lothar Meyer independently developed a periodic table similar to Mendeleev's.However, Mendeleev plotted a few elements out of strict mass sequence in order to make a better match to the properties of their neighbors 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. Mendeleev was later vindicated by the discovery of the electronic structure of the elements in the late 19th and early 20th century.Mendeleev's periodic table also successfully predicted the future discovery of several elements, and has thus become the de-facto standard for the organization and display of the elements.The person you're looking for is Gregor Mendeleev.
Why was Mendeleev's decision to leave blank spaces on his table sometime referred to as his most significant contribution to periodic table?
Mendeleev thought about the future and realized that it was entirely unlikely that all earthly elements had been discovered, so he left blank spaces in his table and even predicted some of the elements that would fit in those spaces. Surprisingly enough, as time passed, chemists began discovering many of the elements that he had predicted, which fit perfectly into his periodic table.

What effect did th discovery of gallium have on the accepteance of mendeleevs table?
Mendeleev had some empty spaces in his table. On being asked why he left spaces, instead of seeing it as a drawback, he confidently said that those were the places for "yet to be discovered elements". He named them by prefixing the Sanskrit numeral "Eka-" to the preceding element.For example, he named Gallium as "Eka-aluminium", Germanium as "Eka-Silicon" and so on. Later, when a new element was found and was named as Gallium, it was observed that it had almost same properties as that of Eka-Aluminium predicted by Mendeleev. As his predictions were almost accurate, other scientists began to accept that his classification was indeed better than any others'. And so, it was accepted.

What is a description of the periodic table?
In 1869 Russian chemist Dimitri Mendeleev formulated the periodic law, which stated that properties of elements recurred in a pattern. Based on this, he also helped develop the periodic table, predicting the discovery of multiple elements rather accurately.
