Get to know the elements

7 February 2019
Celebrating the International Year of the Periodic Table
It’s been 150 years since Russian scientist Dmitry Mendeleev developed the periodic system, and there's a lot to celebrate. Dr Alice Motion shares a little something about each of the 118 elements.

In case you missed it, UNESCO has marked 2019 as the International Year of the Periodic Table of Chemical Elements to raise awareness of chemistry and its application for sustainable development. It also celebrates the 150th anniversary of the discovery of the periodic system by scientist Dmitry Mendeleev in 1869.

Considered one of the most significant achievements in science, the Periodic Table is a tool that scientists and students can use to understand the characteristics of an element from its position on the table, and indeed predict the properties of molecules and materials.

Chemistry lecturer, researcher and science communicator Dr Alice Motion, has taken to Twitter to share interesting facts about each of the elements for the first 118 days of the year.

There’s already a month worth of tweets for you to catch up on, but here are a few to get you started.

Mendeleev published the Periodic Table with known elements arranged in order of atomic mass. He also predicted the discovery of other elements and left spaces open for them on the table.

This is just the beginning of our #IYPT2019 celebrations, keep an eye out for an exciting on campus event which will be part of National Science Week at the University of Sydney.
