what are the origins of the periodic table?

Answer 1

The periodic table of the chemical elements is a tabular method of displaying the chemical elements, first devised in 1869 by the Russian chemist Dmitri Mendeleev. Mendeleev intended the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table has been refined and extended over time, as many new elements have been discovered since Mendeleev's time, and new theoretical models have been developed to explain chemical behavior. Various different layouts are possible to emphasize different aspects of behavior; the most common forms, however, are still quite similar to Mendeleev's original design.

The periodic table is now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize and compare all the many different forms of chemical behavior. The table has also found wide application in physics, biology, engineering, and industry. The current standard table contains 116 confirmed elements."

Answer 5

No because of the fact the periodic table became compiled by human beings and for this reason if a area absent from the periodic table became got here upon in the periodic table then it might in basic terms prepare that there is a before undiscovered factor. besides the undeniable fact that it might could be a heavy factor because of the fact factors with between a million and 118 protons have all been found with out any gaps.

Answer 6

In 1869, a Russian chemist named Dmitri Mendeleev came up with a way of organizing the elements that were known at the time.
He set them out in order of atomic weight, and then grouped them into rows and columns based on their chemical and physical properties.
Mendeleev had no idea what atoms were made of or why they behaved as they did. Nevertheless, he was able to put together the periodic table almost as we know it today--except that some elements were missing, because they were unknown in 1869.
Based on the gaps in his table, Mendeleev even succeeded in predicting the existence and properties of several new elements.
His basic rule was this: the elements in any column, or group, of the table are similar to their column-mates. For example, look at the first column on the left, underneath hydrogen (H). The elements in this group are called the alkali metals; they're all soft metals that react violently with water to make hydrogen gas.
