Unless you're currently taking chemistry, it's probably something you haven't thought. Today is National Periodic Table Day! Scientists have been organizing elements based on their properties since the early 1800s, but the modern day periodic table didn't get its start until about 50 years later. A Russian chemist formulated the periodic law and created a version of the table. The current table features 118 elements. Gold, silver, oxygen and iron are just a few.
The periodic table has actually only just been ‘completed’ in the past year. Four new elements had their discoveries and names confirmed in 2016, and replaced the last few placeholder positions in the table. I say ‘completed’ because scientists are still trying to create elements beyond element 118, so in years to come an extra row may be required to accommodate new element entries.
