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)
What best describes the modern periodic table?
Periodic table of elements.
When the elements are arranged by increasing atomic number there will be a periodic repetition of their propertiesWhich theory is identified by this statement?
No. When the elements are arranged in order of increasing atomic number there is a periodic repetition of their physical and chemical properties.
What is the periodic law?
Periodic Table of elements.
Why are elements put in to 8 groups?
Dmitri Mendeleev (in his periodic table, who arranged according to increasing atomic mass). Niels Bohr in the modern periodic table, where the elements are arranged in increasing atomic number.
How were the elements arranged on his periodic table?
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
Who invented tables?
Lothar Meyer (1864) and John Newlands (1865) both proposed tables that organized elements according to periodic properties. History Most people think Mendeleev invented the modern periodic table.
What is the correct chronological order of scientists contributing to the modern periodic table?
Lavoisier, Dobereiner, Newlands, Mendeleev, and Moseley
Who are the Scientists who contributed in the modern periodic table?
Dimitri Mendeleev produced the first periodic table leaving spaces for elements that were not yet known in 1869; Henry Mosely determined the atomic number of elements and corrected some inaccuracies in Mendeleev's periodic table.
How many elements are in the modern periodic table?
The Periodic Table has 118 elements and counting...
When was the periodic table created and who by?
The periodic table was created by Dmitri Mendeleev in 1869. He organized the elements based on their chemical properties and their atomic weights, creating a system that arranged the elements into groups and periods. This arrangement allowed for the prediction of missing elements and became the basis for the modern periodic table.
How does the modern periodic arrange the elements?
The modern Periodic Table arranges elements based on properties. These properties include valence electrons of the elements and density for example.
What is the similarities in the modern periodic table and Mendeleev's table?
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=

What is the difference between the new and old periodic table?
Well, Back when Medeleev made this table, many of the elements were not even discovered yet. He plotted only the elements that he knew on his table. He organized them by increasing atomic weight. He didn't know all the elements so he would put question marks and empty spaces in the spots he thought elements would be and left to be found by other scientist. He happened to be true about the missing elements and that scientist did end up finding these "missing links" of the periodic table and led to the new or modern periodic table. The modern periodic table doesnt have any missing elements and they changed Medeleev's way of organizing the table by increasing atomic weight to increasing atomic number. So the newer form of the periodic table was complete and made it easier to find what elements react better with other elements. This making the modern table became the more efficent table of our time.
