Introduction

Celebrate National Periodic Table Day on February 7 by learning a little bit more about one of the greatest scientific achievements in history! This day marks the anniversary of when Dmitri Mendeleev first presented his periodic table of elements in 1869. Since then, it has been used as an invaluable tool for predicting and discovering new elements, understanding chemical reactions and properties, and making major advances in chemistry.

National Periodic Table Day Timeline

1869
Mendeleev's Periodic Table
Dmitri Mendeleev publishes his version of the periodic table, arranging elements by atomic weight.
1913
Bohr's Atomic Model
Niels Bohr introduces his atomic model, contributing to understanding atomic structure and influencing the periodic table.
1924
Quantum Mechanics Influence
The rise of quantum mechanics brings a deeper understanding of electron behavior, impacting the modern periodic table´s understanding.
1945
Synthetic Elements Addition
Post WWII, scientists generate synthetic elements for the first time, expanding the periodic table beyond naturally occurring elements.
2016
Most Recent Additions
The elements Nihonium, Moscovium, Tennessine and Oganesson are officially recognized, filling the seventh row of the periodic table.

How to Celebrate National Periodic Table Day

1

Learn about the elements

Take the time to research and learn about each element on the table, what it is used for and what makes it unique.

2

Create a periodic table poster

Make your own poster with all the elements of the periodic table. You can use colors and symbols to make it look more interesting.

3

Watch a documentary

Check out some documentaries online or on TV that discuss the periodic table and its importance in science.

4

Challenge yourself

Put your knowledge to the test by playing some element related games or quizzes.

5

Build an element sculpture

Get creative and make a sculpture using elements from the periodic table.

Why National Periodic Table Day is Important

A

It helps us to study and understand the elements

The Periodic Table provides students and scientists with a standard way of organizing and understanding chemical elements. The table arranges the elements according to their atomic numbers, mass numbers and other properties which help determine how atoms behave in different situations.

B

It is a vital tool for chemistry

The Periodic Table is one of the most important tools in chemistry as it allows chemists to make predictions about the behavior of atoms and molecules based on their position within the table. It also serves as an invaluable reference guide for chemists so they can quickly identify various elements.

C

It is a representation of scientific progress

Beyond its practical applications, the Periodic Table also serves as a powerful symbol of our progress in furthering our fundamental understanding of matter and life. It stands as a testament to centuries of scientific research and exploration into what makes up our universe, and is an ever growing source of knowledge and progress in science.
