Population III (PopIII) stars represent astronomy's ultimate prize: the first generation of stars born from the pristine hydrogen and helium created in the Big Bang. These theoretical giants, ...

Another most interesting discovery is that of helium, which was made by Prof. Ramsay, in 1895, while examining the mineral cleveite for argon, when, besides the spectrum of argon, he observed ...

Helium is the second element in the periodic table, and has the symbol He. Helium is also a gas, but is very different from hydrogen because it doesn’t take part in any chemical reactions.

But, helium isn't the only chemical element being forged in the sun. When and where do stars forge heavier elements? How does nuclear fusion forge the chemical elements?

Helium is one of the least reactive elements on the periodic table. Like the other noble gases, helium doesn’t gain or lose electrons easily and so does not normally form chemical compounds.

Chemical atomicity is governed by distance from the central point of neutrality; mon- atomic elements being one remove from it, diatomic elements two removes, and so on.

“It’s a critical element for the future,” says Richard Clarke, a UK-based helium resources consultant who co-edited a book about the element. Indeed, the European Union includes helium on ...

But this time around, Walker decided to tackle the periodic table of elements. Walker will present his work at ACS Spring 2023, a meeting of the American Chemical Society. Elements emit visible light ...

Chemical cartography shows the distribution of elements throughout the Milky Way — from lighter elements, such as hydrogen and helium, to heavier ones, such as carbon, nitrogen and oxygen.
