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.
In the US soil scientists have devised a system for classifying soils known as the?
Soil Taxonomy
The geologic time scale was devised before numerical dating using radioactivity was invented true or false?
True
In Celsius was 0 always the freezing point of water?
The Celsius temperature scale was changed to its current status shortly after the death of Anders Celsius, who devised the system. Until then, 0 degrees was the boiling point of water and 100 degrees was the freezing point. (see: http://www.answers.com/topic/celsius)
When was earth diameter first estimated?
Eratosthenes of Cyrene (276 BC - 194 BC) was a Greek mathematician, poet, athlete, geographer and astronomer. He made several remarkable discoveries and inventions: he devised a system of latitude and longitude. He was the first person to calculate the circumference of the Earth with remarkable accuracy, and the tilt of the earth's axis.
Did a Russian the early periodic table?
The arrangement of chemical elements into the widely recognised periodic table was first devised by the Russian chemist Dimitri Mendeleev.
What pattern did Mendeleev find while organizing information on the elements Answer NOW?
Mendeleev was the scientist who first devised the periodic table of the elements. The pattern he found was that elements have periodic, or repeating series of properties. If you write down the elements in a series according to increasing atomic number, there is a repeating pattern; first metals, then nonmetals, then noble gases, then back to metals. This pattern helps us to understand why elements have the particular chemical properties that they have. It is fundamental to the science of chemistry.

Why is the periodic table arranged in terms of electrons?
It is because Mendeleev based his periodic table on the elements being arranged from lightest to heaviest. It also makes more sense to have the reactivity arranged effectively and metals and nonmetals categorised together.
Who devised the periodic table of elements?
Dmitri Ivanovich Mendeleyev. Another spelling of his name is Dmitri Ivanovich Mendeleev.
Julius Lothar Meyer its contribution to the development of the periodic table?
Julius Lothar Meyer devised a classification of elements into a table that accounted for the periodic variation in properties. his table included 56 elements.

What is an example sentence using the word devised?
He devised a new technique using his technologies. This is an example of sentence using devised.

the first machine devised by humans is "abacus".
How was the person who devised the first periodic table able to predict the behavior of elements such as gallium scandium and germanium that had not even been discovered yet?
The reason the periodic table was created in the first place was to illustrate the "periodic" physical properties of the known elements of the time. Because of this, the properties of elements that were "missing" from the table could be extrapolated from the periodic trends seen in the known elements.
