The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

Salt may be the most routine ingredient in the world. It would be difficult to find a kitchen without it in some form. Table salt is the most common, and it comes from extracted salt from underground ...

The quantity of thorium lead per gram of thorium is 0.0062, and this, divided by the rate at which the lead is being produced, 4.72 x l^—11 grams of lead per gram of thorium per year, gives the ...

For example, Lead is a chemical element with the symbol Pb (from the Latin for lead, plumbum).W stands for tungsten (from the word wolfram) and Na stands for sodium (from the word natrium).

The periodic table looks complete, but it isn’t. The race is on to discover the table’s next row of elements, starting with elements 119 and 120. Japan hopes to produce element 119 one atom at ...

Since Mendeleev's time, scientists have discovered new elements, expanding the periodic table. The most recent additions include nihonium, moscovium, tennessine, and oganesson, which were officially ...

Chemists from The University of Manchester and The Australian National University (ANU) have engineered a new type of ...

Mendelevium was the first element identified on an “atom-at-a-time” basis and the heaviest element to be first identified by chemical separation. With the completion of the heavy ion linear ...

In the European Physical Journal Plus, Rafelski and two colleagues mathematically demonstrated that the existence of CUDOs (compact ultra dense objects) do not have dark matter, but are filled with ...

The James Webb Space Telescope and other observatories witnessed a massive explosion in space that created rare chemical elements, some of which are necessary for life.
