Meeting the challenge around the world

How to get to the Nobelium Contest?

In order to submit your entry to the Nobelium Contest you must first play the IUPAC Periodic Table Challenge.

Complete the 15 question Challenge about the chemical elements and score at least 60 % correct answers (9 questions). Do not worry if you cannot do this in a single try – you can play as many times as you like. Feel free to use internet to find out the answers. In fact, we encourage you to play as many times as you can because each time you will get different questions. The email address you provide will keep track of your progress.

About this Challenge and IUPAC100

The year 2019 marks the 100th anniversary of IUPAC and also the 150th anniversary of the development of the Periodic Law of the Elements independently by Dmitri Mendeleev and Lothar Meyer.

To celebrate these anniversaries, IUPAC is hosting an online challenge about the Periodic Table of the Elements aimed at a global audience of young students. Our goal is to reach players from every country. The challenge runs from January 2019 and will be available all year until the end of 2019.

The IUPAC Periodic Table Challenge will present you with 15 randomly chosen multiple-choice questions about the elements. To play, you will be asked to choose an element as avatar. Your score will go towards this element in the leaderboard. When you finish the challenge, you will be asked to provide your name and email so we can keep track of your achievements. Please enter your name and email after finishing the Challenge: without it your efforts will not reach us.

Schools, Institutions, or Organizations may wish to participate in the Periodic Table challenge and have a way to find out who, among its members, has achieved the highest scores. Please read more about this option in the Rules and Procedures.

The Challenge is in English and if you have difficulties in understanding some of the questions, please copy the text and use online translation tools to help.

Share your experiences on social media using #PeriodicTableChallenge or #iupac100.
