About National Periodic Table Day
Science lovers and chemistry enthusiasts, grab your lab coats! Every February 7th, we celebrate National Periodic Table Day.
This isn't just a day for students to sweat over memorizing atomic numbers; it’s a celebration of one of the most significant achievements in science—a map of the universe’s very building blocks.
Why is National Periodic Table Day on February 7th?
The date, February 7th, wasn't chosen at random. It marks the anniversary of the first publication of the periodic table by English chemist John Newlands in 1863.
While his "Law of Octaves" was initially met with some skepticism, it paved the way for Dmitri Mendeleev to create the version we are more familiar with today.
The table is a masterpiece of organization, grouping elements by their properties and atomic structures, making it an essential tool for understanding how our world works at a molecular level.
Did you know? Dmitri Mendeleev was so confident in the logic of his table that he left empty spaces for elements that hadn't even been discovered yet, correctly predicting their properties!
Marking National Periodic Table Day
Getting involved in National Periodic Table Day is a great way to spark some curiosity and have a bit of fun with science. Whether you are a student, a teacher, or just someone who enjoys a good "elemental" pun, there are plenty of ways to participate:
Brush up on your basics: Take a few minutes to look at a modern periodic table. You might find some surprising elements you didn't know existed, like Oganesson or Tennessine.
Wear your science on your sleeve: Many people celebrate by wearing T-shirts featuring their favorite element or their name spelled out using elemental symbols (like Carbon, Arson, and Tin for "C-As-Sn").
Try an "elemental" snack: Bake cookies decorated with atomic symbols or arrange a snack tray where the colors represent different groups like noble gases or alkali metals.
Visit a science center: Many museums and universities host special events or displays to honor the history of chemistry.
Did you know? There are 118 confirmed elements on the periodic table today, but only 94 of them occur naturally on Earth. The rest are synthetic, created in laboratories.

If you're feeling ambitious and want to master the table yourself, here is a simple way to get started:
Start by learning the first ten elements to build your confidence.
Group the elements by their "families" (columns), as elements in the same group often share similar behaviors and traits.
Use mnemonic devices or songs—there are plenty of catchy tunes online that make memorization much easier!
Practice by identifying elements in everyday objects, like the Aluminum in your soda can or the Neon in a storefront sign.
No matter how you choose to celebrate, National Periodic Table Day is a reminder that everything—from the stars in the sky to the phone in your hand—is made of the same fascinating stuff.
