Update (Thu Jul 13 2023): The Periodic Table Calculator has been updated so that it uses rounded rectangles. I also fixed a spelling mistake where "unknown" would be spelled as "unkwown". To see the previous version, click here.

I completed the original Periodic Table Calculator in July, 2018, when I was six. It would not be possible if not for Khan Academy's online tutorial for JavaScript. I'm very much thankful to my family and this program is dedicated to my Dad and Mom.
