Daily 40 no. – 16 Dmitri Mendeleev

Daily 40 Hall of Fame! Congratulations to these writers! Dmitri Mendeleev (1834-1907) was born in Tobolsk, Siberia. Mendeleev found that when arranging the elements in increasing atomic mass, their chemical properties demonstrated definite trends. Not only did he create this first periodic table, but he left space for new elements, and predicted three yet-to-be- discovered elements including eke-silicon and eke-boron. --Gennelle

Dimitrii Mendeleev wan born in Verhnie Aremzyani village February 8, 1834, and died February 2, 1907. He created a version of the periodic table of elements, but unlike Newland’s form, he left spaces for new elements. His main flaw was that he did not account for transition metals. --Eyad

Unlike Newlands, Dimitrii Mendeleev (1834-1907) left gaps in his table of elements and predicted the unknown elements by their atomic weights. However, his table did not have the transition elements correctly positioned. Mendeleev also used his table to correct the accepted atomic weights of elements. - -Dee Dee

Russian chemist Dmitri Mendeleev (1834-1907) created an improved periodic table of the elements that, unlike Newlands’s, left room for undiscovered elements. Mendeleev was able to predict the discovery of scandium, gallium, technetium, and germanium, though he incorrectly stated that elements’ atomic masses are always arranged in increasing order. --Chantal

Dmitri Mendeleev (1834-1907) was a Siberian chemist who made great contributions to the modern periodic table. He ordered all of the elements by atomic weight and grouped them by similar properties. He also guessed the existence and properties of undiscovered elements and pointed out accepted atomic weights that were erroneous. --Alanna

Dmitri Mendeleev was a Russian chemist known for creating the first periodic table, which left spaces for undiscovered elements, unlike Newlands. With his table Mendeleev was able to predict the properties of undiscovered elements on the table. He is credited with introducing the metric system to Russia. --Andrew

Dmitri Mendeleev lived in Russia from 1834-1907. He delivered a speech called “The Dependence between the Properties of the Atomic Weights of Elements,” explaining how the behavior of elements correspond to their atomic weights. In addition, Mendeleev left space on a progressing periodic table for elements yet to be discovered. --Christine

Dmitri Mendeleev of 19th century Russia is the credited creator of the first version of the periodic table of elements. He arranged the elements in order of increasing atomic weight, but unlike Newlands he left space for undiscovered elements (scandium, gallium, and geranium) and predicted their properties. --Dawy

Dimitrii Mendeleev (1834-1907) a Russian chemist was accepted as being maker of the first version of the period table. His elements were ordered by atomic weight, but he left spaces for the elements yet to be discovered while also predicting the properties of undiscovered elements. --Denise

Daily 40 no. – 16 Dmitri Mendeleev

Dimitrii Mendeleev, a Russian chemist who lived from 1834 to 1907, created a periodic table ordered by atomic weight, but left blank spaces where elements were not discovered yet. Thus, he was able to predict properties of unknown elements. This led to understanding about similarities between different elements. --Eric

In Russia, Dimitrii Mendeleev lived from 1834 to 1907. He created a periodic table by arranging the known elements, according to their atomic weights, into seven groups. Later, the discovery of three predicted elements: gallium, scandium, and germanium strongly supported his periodic table. The element Mendelevium was named after him. --Isaac

Dimitrii Mendeleev(1834-1907) was a Russian chemist. He is credited for creating the first comprehensive periodic table. Mendeleev classified the elements based on size, magnitude, and valencies. He correctly placed the lanthanide series and predicted the existence of an actinide series. His organization of the elements was vital to future chemistry. --Jaya

Dmitri Mendeleev (Russian, 1834 – 1907) is famous for creating the first version of the periodic table. Mendeleev’s table listed the elements in order of atomic weight, and although the table was not complete yet, he left spaces and predicted the properties of Germanium, Gallium, and Scandium. --Jeff

Mendeleev (1834-1907) was a Russian chemist who is known for making the first version of the periodic table. His table was organized in order of atomic weight and valence, by observing patterns in the table he was able to predict properties of undiscovered elements. --Julia

Dimitri Mendeleev (1834-1907) was a Russian chemist and inventor. He was credited to organize the elements in a logical way. Because of his organization he was able to predict other elements, such as germanium, scandium, and gallium. His work help create the periodic table that we use today. --Karen

Dmitri Mendeleev was a Russian chemist who lived from 1834 to 1907. He was greatly influenced by Newlands in the sense that he made a table organized by atomic weight, and predicted the discovery of elements like germanium and scandium, however, he left space for these in his table. --Katy

Dmitrit Ivanovich Mendeleev, a nineteenth century Russian chemist, formulated the first version of the periodic table, which allowed chemists to predict properties of unknown elements and re-evaluate the relationship between atomic mass and physical properties. He also published his work on water and alcohol mixtures, the spectroscope, and studied petroleum. --Madeline

Dimitri Mendeleev (1834-1907) is a Siberian chemist well known for the periodic table he organized by atomic mass and elements classified by their similar properties. What differed from the other chemists was that he left spaces for undiscovered elements. It is similar to the periodic table we have today. -- Tatiana

The first version of the periodic table is credited to Russian chemist Dmitri Mendeleev. In 1868, he wrote the Principals of Chemistry, which classified elements according to their properties. In 1870 he presented the Dependence between Properties of the Atomic Weights of the Elements, which described atomic weights and valances. --Tokunbo

Daily 40 no. – 16 Dmitri Mendeleev

D.I. Mendeleev was a Russian chemist and inventor of the first version of the periodic table. In 1869 in one of his major publications he hypothesized elemental patterns through repeating properties and insinuated the presence of unidentified elements and accounted for them via spaces in his periodic table. --Victoria

Dimitrii Mendeleev, a Russian, lived from 1834-1907. He is credited with being the creator of the first periodic table of elements. While trying to classify the known elements, he noticed trends that led him to create the periodic table. He also predicted elements that would fill in missing spots. --Yulan
