National Periodic Table Day

Since 2016, February 7 has been dedicated as National Periodic Table Day, a celebration that honors the essential chart we often relied on in our high school chemistry classes to help us pass those tricky exams! The inspiration for this special day came from the brilliant mind of Mr. David T. Steineker, a chemistry teacher who likely had a few academic motives up his sleeve. Regardless of his reasons, this day is all about appreciating the periodic table and the scientists behind it, who have laid the groundwork for ongoing scientific discoveries. If you’re interested in exploring scholarships in various scientific fields, this could be your chance to discover your potential.

The Origin of National Periodic Table Day
Without the periodic table, many of us might not have breezed through our chemistry tests. Ironically, that same table is what made chemistry seem so daunting in the first place! Yet, we cannot overlook the revolutionary changes that the periodic table has introduced to the world of chemistry. On February 7, 2016, Mr. David T. Steineker established National Periodic Table Day to commemorate the publication of John Newlands’ periodic table of elements, which debuted on February 7, 1863. Notably, this day also marks the birth of Dmitri Mendeleev, the Russian chemist credited with creating the modern periodic table in 1869. Mr. Steineker’s initiative aimed to celebrate and challenge the discoveries tied to the periodic table, acknowledging the contributions of many scientists since the 19th century.

It’s essential to recognize the foundational work done by German chemist Johann Dobereiner, who, in 1817, began organizing elements into groups of three based on their similar properties. Along with Swedish chemist J.J. Berzelius, Dobereiner discovered the first catalyst through experiments involving hydrogen ignition and potassium powder. Following that, John Newlands, an English chemist, published the first periodic table in 1863, grouping 56 elements into 11 categories. Although his table had some flaws, he was the first to introduce the ‘Law of Octaves.’ Thus, National Periodic Table Day honors the scientists who provided us with this simplified model, enabling chemists to predict element behavior at a glance.

Key Milestones in Periodic Table History

• 1817: Johann Dobereiner’s Initial Grouping
  Dobereiner classifies elements into triads based on shared characteristics.
• 1863: John Newlands’ Pattern Discovery
  Newlands becomes the first to identify a pattern among elemental properties.
• 1869: Mendeleev’s Groundbreaking Table
  Dmitri Mendeleev publishes a table with 60 of the 100 known elements, organized by atomic mass.
• 1904: Noble Gases Uncovered
  William Ramsay, a Scottish chemist, discovers four noble gases and earns a Nobel Prize.
• 1913: The Modern Periodic Table
  Henry Moseley, an experimental physicist, identifies that each element has a unique proton number, adding four new chemical elements to the table.
• National Periodic Table Day FAQs
  • Why was 2019 declared as the International Year of the Periodic Table by UNESCO?
    This year marked the 150th anniversary of the periodic table’s creation by Dmitri Mendeleev.
  • Who is known as the father of the periodic table?
    Dmitri Mendeleev.
  • Why does the periodic table have its unique shape?
    Its castle-like layout allows scientists to easily observe each element and its properties.
  • Fun Activities for National Periodic Table Day
    • Trivia Challenge: Test your knowledge about the periodic table with friends and family. Ask about the elements in rust, potassium’s symbol, or argon’s atomic number.
    • Periodic Table Scrabble: Gather your friends and a periodic table chart. Create real words using element symbols and keep score based on atomic numbers. For example, the word “CaSe” could score 54 points!
    • Sing the Periodic Table Song: Have you ever tried singing the periodic table song? Today is the perfect opportunity! It might be amusingly annoying, but it’s a fun way to remember those challenging chemistry days!

    Five Fascinating Facts About the Periodic Table

    1. Missing a Letter: The periodic table includes every letter except for J.
    2. Battery Weighting: Early scientists used batteries to weigh atoms according to their polarities.
    3. Element Names: Uranium is named after Uranus, while argon comes from the Greek word ‘argos,’ meaning ‘idle.’
    4. Carbon, the King: Carbon is often dubbed the king of elements because it can form four covalent bonds with other elements and itself.
    5. Francium’s Rarity: There are only a few ounces of francium on Earth, making it the rarest element.

    Why We Cherish National Periodic Table Day

    • Chemistry’s Building Blocks: The periodic table is hailed as “chemistry’s most significant breakthrough.” It provides insight into the molecular makeup of matter and has led to innovations in various applications.
    • Cancer Treatment: The rare compound Taxol, derived from Pacific yew trees, has been synthesized to treat cancer effectively.
    • Flat Screen Technology: The development of liquid crystal displays owes its success to a molecule called 5CB, which replaced older cathode ray tube technology.
