The journey of the elements starts in the earliest moments of the Big Bang, when our universe was only a few seconds to a few minutes old. When you purchase through links on our site, we may earn an ...

In their momentary life span, atoms of lawrencium, element 103, may have left a lasting impression on the structure of the periodic table. For the first time, researchers have measured a basic ...

New insight into the behaviour of atomic nuclei may explain how gigantic star explosions, or supernovas, have formed the elements that are crucial to humankind. Ground-breaking research in nuclear ...

How are chemical elements produced in our Universe? Where do heavy elements like gold and uranium come from? Using computer simulations, a research team from the GSI Helmholtzzentrum für ...

Researchers have detected fluorine -- an element found in our bones and teeth as fluoride -- in a galaxy so far away that its light has taken over 12 billion years to reach us, a discovery that is ...

Inscribed on an Italian family’s 15th century coat of arms and decorating an ancient Japanese shrine, the Borromean rings are symbolically potent. Remove one ring from the trio of linked circles and ...

Sodium is in group 1. A sodium atom has one electron in its outer shell. The atom is more stable if it has a full outer shell. A sodium atom can lose its outer electron. It will still have 11 positive ...

Elements in group 1 and group 2 are metals. Atoms of group 1 elements have one electron in their outer shell, and atoms of group 2 elements have two electrons in their outer shell. Elements in groups ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

Element 117, first discovered by Lawrence Livermore scientists and international collaborators in 2010, is one step closer to being named. The existence of element 117 and its decay chain to elements ...

Scientists at Lawrence Berkeley National Laboratory (LBL) have formally retracted their claims for the discovery of the most massive chemical element. The synthesis of the "superheavy" element 118, ...
