5. Did Mendeleev’s periodic table miss anything? When argon was discovered in 1894, it didn’t fit into any of Mendeleev’s columns, so he denied its existence — as he did for helium, neon, krypton, ...

Helium is the second-most common element in the universe, but it's comparatively rare on Earth. It also fulfills a surprising role in everything from space exploration to quantum computing.

Partisans are clashing over which elements belong in group 3, where helium should go, and how many columns the periodic table should have. They follow a long line of chemists and physicists who ...

Qatar is the world’s second-biggest producer of helium, the gaseous element that sits at the top-right of the periodic table. You may be wondering, what’s the big deal? Is it so bad if ...

Helium, a noble gas, was long believed to be 'too aloof' to react with the other elements on the periodic table. Now, however, scientists have provided a theoretical explanation of how helium may ...

Physicists develop a 'nuclear periodic table ... Among these are familiar elements such at helium, oxygen, and calcium. The Nucletouch table places these 'magic nuclei' at its center, providing ...

We're all familiar with the elements of the periodic table, but have you ever wondered ... And while simpler spectra like hydrogen and helium, which only have a few lines in their spectra, sound ...
