created it.In 1869,Dmitri Mendeleev published the very first periodic table.Although there were a few people who attempted to cre-ate a periodic table, Mendeleev's table was the mostcomplete of all of them.Dmitri Mendeleev was born on February 8,1834 inTobolsk Governorate, the Russian Empire...
First only about 60 elements had been discovered (we now know of over 100) and second some of the information about the 60 was wrong. It was if Mendeleev was doing a jigsaw with one third of the pieces missing, and other pieces bent! Mendeleev had written the properties of elements on ...
B Anyone who has ever taken chemistry has studied the periodic table (元素周期表). Most people who have memorized the elements in the periodic table have probably not given any thought to who created it. In 1869, Dmitri Mendeleev published the very first periodic table. Although there were a...

Some elements were known since ancient times, such as gold, sulfur, and carbon. Alchemists began to discover and identify new elements in the 17th century. By the beginning of the 19th century, about 47 elements had been discovered, providing enough data for chemists to begin to see patterns...
Atomic mass:The standard atomic weight of an element is the average mass of the element written in atomic mass units (amu). Even though each atom has roughly a whole number of atomic mass units, you will notice that the atomic mass on the periodic table is a decimal; that's because the...
27. Who is the father of the periodic table? Dimitri Mendeleev Niels Bohr Ernest Rutherford None of the above Answer The correct answer is:A) Dimitri Mendeleev Explanation Russian chemist Dmitri Mendeleev is generally credited with developing the first widely accepted periodic table of elements. He...
the periodic table stretch back to at least as early as 1669 when German merchant Hennig Brand created the Philosopher’s Stone, 1680 when Irishman Robert Boyle discovered phosphorus, and 1863 when English chemist John Newlands divided 56 known elements into 11 groups based on their characteristics...
