Dmitri Mendeleev created the first Periodic Table according to Atomic Mass in 1869. Others before Mendeleev had organized the elements according to their properties and were able to discern periodicity, although Mendeleev is generally accepted as the creator of the table.
With the information he gathered about the elements, he was able to see that there were missing elements that hadn't been discovered. He could figure out the atomic masses of the missing elements by averaging the atomic masses of the elements above and below the missing one. One such element, which he called "eka-silicon" (eventually Ge) was missing, but with understanding of the patterns the periodic table made, he predicted the elements appearance, melting point, atomic mass, density, formula of oxide, and formula of chloride.
Throughout the years, other scientists were able to find or create these missing elements to form the table we know today. Today's periodic table is ordered by atomic number instead of atomic mass (as Mendeleev had started). Henry Moseley was the first to order the elements by atomic number so elements would fit together in groups/families and periods better in 1913.

Who invented the decimal notation in arthimetic?
This system was originally invented in India in the 6th century AD (or earlier), and was soon adopted in Persia and in the Arab world. Persian and Arabian mathematicians made many contributions (including the concept of the decimal fractions as an extension of the notation), and the written European form of the digits is derived from the ghubar (sand-table or dust-table) numerals used in north-west Africa and Spain.
Who is credited with inventing multiplication?
There was not a single person credited with inventing multiplication. Egyptians, Babylonians, and Chinese all had their own methods. John Leslie invented the multiplication table.
Who invented the multiplication table?
The multiplication table as we know it today was not invented by a single individual, but rather developed over time through mathematical advancements. The concept of multiplication itself dates back to ancient civilizations such as the Egyptians and Babylonians. The modern layout of the multiplication table, with rows and columns listing the products of numbers 1-10, became standardized in the 19th century as part of elementary mathematics education.
Who invented the Multiplication Table on Rods?
Multiplication table has its origin from simple mathematical table.Mathematical tables can be traced backed to 1900 BC in the Babylonian mathematics in the clay tablets found one of the most important tablet is named as Plimpton322.Then the Greek Astronomer Hipparchus used Trignometric Tables those can be the multiplication table in some sense.Those may be the Greeks who developed multiplication tables on road around 200BC. Pythagoras.

Is there a Le on the piriodic table?
No, there is no element with the symbol "Le" on the periodic table. The periodic table lists all known elements and their symbols, but "Le" is not one of them.
