National Periodic Table Day for the year 2024 is celebrated/observed on Tuesday, February 7th. There are until the next observance.

Since 2016, February 7 has been designated as National Periodic Table Day to honor the chart put in science classrooms that spared us from failing high school chemistry! Mr. David T. Steineker, a chemistry instructor, came up with the brilliant idea of dedicating a day to saluting the periodic table and its scientific innovations, and we can’t help but suspect that he had some sly ulterior (read: academic) intentions behind it. Whatever the cause, we praise and laud the periodic table and its scientists on this day for being the crucial building blocks (literally) for continuous scientific discoveries. Applying for scholarships in science is a great way to find out what you can do in the field.

📜 History of National Periodic Table Day

Mr. David T. Steineker, an author, inventor, and chemistry teacher at Jefferson County Public School in Kentucky, established National Periodic Table Day on February 7, 2016 to commemorate the publication of scientist John Newlands’ periodic table of elements on February 7, 1863. Dmitri Mendeleev, a Russian chemist and physicist best known for developing the modern periodic table in 1869, was also born a day before February 7. Mr. Steineker suggested making a day to remember and talk about the discovery of the periodic table of elements, which has been credited to more than one scientist since the 1800s.

It is immoral not to acknowledge the original foundation of the periodic table, which was set down by the German scientist Johann Dobereiner in 1817. Doberiener and Swedish chemist J.J. Berzelius developed the first catalyst by working with hydrogen ignition and potassium powder. He put together groups of three parts that had similar qualities. This gave other scientists a place to start making changes.

Then there was John Newlands, an English chemist. In 1863, he presented the first periodic table, which classified 56 elements into 11 groups. While Newlands’ periodic table had certain flaws, he was the first to propose the “Law of Octaves.” So, National Periodic Table Day honors the scientists who made a simplified model of the elements that can be used as a quick reference and lets chemists predict how elements will act just by looking at them.

☑️ National Periodic Table Day facts

Battery polarity was used to weigh atoms
At the time, scientists utilized batteries to separate all 63 atoms based on their polarities, and each atom was then weighed in its own container.

Elements are named after various things
Uranium was named after Uranus, but argon is derived from the Greek term argos, which means “idle.”

The king of the periodic table is carbon
Carbon is regarded as the king due to its ability to establish four covalent connections with other elements as well as with itself.

Things to do on National Periodic Table Day

Play the Periodic Table Day trivia challenge
Learn about the periodic table and participate in a quiz contest with friends and family. Find out about facts and numbers like how rust is made, what the symbol for potassium is, or what argon’s atomic number is.

Play a periodic table scrabble game!
Gather your buddies, a pen and paper, and a periodic table chart in the center. Make good English language words out of element symbols and write them down. The player with the most points at the conclusion of the game wins. But how can we define the scoring rules? The atomic numbers of each element, of course! For example, the word “case” is composed entirely of components and adds 54 points to your name.

Sing the periodic table song with friends
Have you ever heard the song about the periodic table? Today is the day! It’s both annoying and entertaining, but it’s a memorable way to recall the awful chem-exam days!
