It is one of the highlight learning materials for some students, but for some it is one of the hardest table to deal and learn during their Chemistry classes.
Periodic Table of Elements is a tabular arrangement of elements based on atomic number, electron configurations and recurring chemical properties.
It has 118 elements and first introduced in the late 1800s by a Russian chemist.
In 1869, when the Periodic Table was invented by Russia’s Dmitri Mendeleev, since then it was used by all researchers, students and scientists in studying elements – in school or research.
The United Nations has designated 2019 as the International Year for Periodic Table to celebrate “one of the most significant achievements in science”.
In March, it will be 150 years since the Russian scientist, Dmitri Mendeleev, took all of the known elements and arranged them into a table.
Most of his ideas have stood the test of time, despite being conceived long before we knew much about the stuff that makes up matter.
The milestone for the century-old table “birthday” celebration will be kicked off in Paris.
You what’s your memorable experience in studying “Periodic Table” during your Chemistry time?
