Our Favorite Elements
My
Favorite
The United Nations has declared 2019 the International Year of the Periodic Table in honor of the 150th anniversary of that chart of the chemical elements. To celebrate, our friends at Lawrence Berkeley National Lab launched a video campaign highlighting scientists and others talking about their favorite elements—shared on social media with the hashtags #MyFaveElement and #IYPT2019. We’re joining in with this interactive chart of Brookhaven Lab staff’s picks. Click on any blue element below to learn who liked it and why. Some choices relate directly to our research; some are personal preferences; and some are just for fun!
