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.
The geologic time scale was devised before numerical dating using radioactivity was invented true or false?
True. The geologic time scale was established based on relative dating principles before the development of numerical dating methods using radioactivity in the 20th century.
In the US soil scientists have devised a system for classifying soils known as the?
Soil Taxonomy system, which categorizes soils based on their properties, composition, and characteristics. This system helps soil scientists understand and communicate information about soils more effectively, enabling better land management and resource conservation.
Where did Fahrenheit get its name?
Fahrenheit (symbol °F) is a temperature scale based on one proposed in 1724 by the German physicist Daniel Gabriel Fahrenheit (1686-1736), after whom the scale is named.
Devised a scale to test the hardness of minerals?
The hardness of minerals is commonly tested using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch each other. The scale was devised by Friedrich Mohs in 1812 and is still widely used in geology and mineralogy for identifying and comparing the hardness of different minerals.
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 is the contribution of de chancourtois?
De Chancourtois is known for his contribution to the development of the early periodic table of elements. He arranged the elements in a spiral or helical format based on atomic weights, which foreshadowed the modern periodic table structure. This arrangement helped in understanding the periodic trends and relationships between elements, paving the way for the organization of elements we use today.
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.

What was mendeleev's dream?
The story goes.... In the search for the relationship between the known elements, Dmetri Mendeleev's devised a card game made of elements; sort of like 'elemental solitaire'. In this game, each card had one element written on it with its atomic weight. He spent 2 sleepless days attempting to find a relationship by grouping the cards together on the table. On the third day there was a snow storm and Mendeleev's decided to stay home. Although restless he eventually fell asleep in which he dreamed a scientific breakthrough. In this dream he saw the elements arranged in a table and they were grouped together by various properties. When he awoke, he attempted to group the known elements in this manner and noticed that in order for this arrangement to work, he needed to leave spaces or gaps for other elements. Therefore, he also discovered that there were many other elements needed to be discovered.
Who devised the periodic table of elements?
Dmitri Ivanovich Mendeleyev. Another spelling of his name is Dmitri Ivanovich Mendeleev.
A sentence using the word devised?
You devised a question using the word devised. Scientists devised a method of measuring ozone in the upper atmosphere.
When was Chinese astronomy devised?
It was devised in pre-history.
Is devised a verb or noun?
"Devised" is a verb, an action word.
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.
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.
What was the first machines devised by humans?
the first machine devised by humans is "abacus".
