The last major changes to the Periodic Table resulted from Glenn Seaborg's work in the middle of the 20th Century. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements from 94 to 102. He reconfigured the periodic table by placing the actinide series below the lanthanide series. In 1951, Seaborg was awarded theNobel Prize in chemistry for his work. Element 106 has been named seaborgium (Sg) in his honor.

Although Dmitri Mendeleev is often considered the "father" of the periodic table, the work of many scientists contributed to its present form.

The Russian chemist Mendelev was the founder of the modern periodic table, but many scientists who have discovered new elements have added to it.

How was mendeleev's scheme for listing elements different from that used in the modern periodic table?

Mendeleev's scheme was different from the modern periodic table because he listed the elements in order according to the relative atomic mass. Dmitri Mendeleev created his periodic table in 1868.


Elements that have some metallic and nonmetallic properties are known as?

Elements with properties of Metals and Non-metals are shown in the periodic table in the "stairs" which is the pattern seen on the right hand side of the periodic table consisting of the elements, Boron; Silicon; Germanium; Arsenic; Antimony; Tellurium; and Pollonium, that is according to the modern day periodic table. These elements are known as metalloids. Richard hope tht helps :D x


When did Dmitri Mendeleev create the modern periodic table?

Mendeleev first created the periodic table in 1869. He thought that the elements must be organised in some way, that we would be able to use for experiments. And he first thought of the periodic table. He tried and tried but could not get them all to fit. He stayed up for hours, until finally giving up late at night. But when he went to bed, he did not know that just hours later, he would make one of the biggest discoveries yet... He went to bed and dreamed about the periodic table. Then, he dreamt of one only possible way too make the elements fit together. He suddenly woke up, and put all his cards in place, and the periodic table was made.


How would you use element in a sentence in science?

That element is found as a solid in nature.We studied one element every day in science class. Hydrogen is an element.


What is difference between periodic and non-periodic changes?

Changes that repeat themselves after a fixed interval of time are periodic changes. eg. day and night formation. Changes that do not repeat themselves after a fixed interval of time are non periodic changes.eg. tornado i.e. a natural calamity.

In the modern day periodic table, the periodic table gets wider in periods two, four, and six.


Who contributed ideas to the modern day periodic table?

How is the table of elements you prepared similar to the modern periodic table?

Yes, modern day periodic table was based off of Mendeleev's. The difference is that the modern day periodic table is arranged by atomic number, and Mendeleev's was arranged by atomic mass.


Where the periodic table was discovered?

The periodic table was first proposed by a Russian chemist Dimitri Mendeleev. The modern periodic table ordered by atomic number was proposed by an English physicist, Henry Moseley.


How does the modern day periodic table of elements differ from Mendeleyevs chart?

Which were the elements predicted by Mendeleev and what name did he give them?

Dmitri Mendeleev figured out that there were missing elements on his periodic table. Using periodic trends and averaging numbers, he could make pretty accurate predictions about elements not discovered yet. Mendeleev predicted four: * ekaboron (modern day scandium) * ekaaluminium (modern day gallium) * ekamanganese (modern day technetium) * ekasilicon (modern day germanium)


How many elements on the Periodic Table do you use every day?

What is the difference in the modern periodic table and Mendeleev's table?

The periodic table is now complete and can be displayed using the integral atomic numbers. In Mendeleev's time there were still unknown elements. In fact, one of the primary uses of his table was to predict the properties of elements that had not yet been isolated. (His 1869 table included speculative names for some expected elements.) -- In Mendeleev's periodic table, transition elements were placed in another group. --In Mendeleev's periodic table, noble gases were written on left side. In the modern periodic table, noble gases are written on right side.


What contributions to science were made by Dmitri Mendeleev?

He invented the periodic table. You must know what that means; he was the father of basic chemistry. Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.


What are the major contributions of the alchemists to science?

Their attempts to arrange information on substances so they could clarify and anticipate the products of their chemical reactions, resulted in them laying down the foundation for the modern day periodic table of elements.
