The classic Mendeleev periodic table sorts elements by number of electrons and then in groups that indicate how readily their atoms bond with others. That bondability factor is based on shell ...

The periodic table of elements has been an absolute runaway success for 150 years. Now, a team wants to try it with molecules. Here's what it would look like.

Still, the groups have a lot to be proud of, according to Jimmy Franco, an organic chemist at Merrimack College who helped lead an effort to paint the world’s largest periodic table in 2012.

The periodic table is a good example of how scientific ideas develop over time. Mendeleev left gaps in his table when he drew it up in 1869, using his insights to predict that scientists would ...

The researchers describe their method as analogous to the periodic table of chemical elements, which groups atoms based on how they bond to each other. However, the researchers say that in order to ...

This year, the periodic table of chemical elements celebrates its 150th birthday. As the candles on the cake are lit, it's time to test your knowledge, with our quiz.
