It's elemental

Since 2016, National Periodic Table Day has been celebrated on February 7 to pay tribute to the chart pasted in science classrooms that saved us from flunking high school chemistry! The idea to dedicate a day to toast the periodic table and its scientific inventions was conceived in the clever mind of a chemistry teacher, Mr. David T. Steineker, and we cannot help but assume that he had some sneaky ulterior (read: academic) motives behind it. Whatever the reasons, on this day, we celebrate and glorify the periodic table and its scientists in being the critical building elements (literally) for the continuing discoveries in science.

John Newlands was an English chemist who published the first periodic table in 1863, which organized 56 elements into 11 groups. While Newlands’ periodic table was slightly flawed, he was the first scientist to introduce the ‘Law of Octaves.’ National Periodic Table Day, thus, honors the scientists who created a simplified model that gives us an easy reference and helps chemists anticipate the behavior of elements within a glance.

An experimental physicist Henry Moseley discovers that each element had a separate proton number, leading to the addition of 4 new chemical elements the modern periodic table in 1913.

The first Attempt at Making of Periodic Table took place in 1817 when John Dobereiner organizes elements into a triad (groups of three) based on similar properties.

In 1869 Dmitri Mendeleev published the periodic table containing 60 of the 100 elements we know today, arranging them according to their atomic masses.

Scottish chemist William Ramsay discovers four noble gasses (neon, argon, krypton, and xenon) and wins a Nobel prize in 1904.

This is all I remember of high school chemistry class:

This is kinda scary.     Picture of the shirt I put on this morning.   Long before reading Richard's daily.
