Unfortunately for Meyer, his work wasn’t published until 1870, a year after Mendeleev’s periodic table had been published. Even after 1870, Meyer and Mendeleev were still unaware of each other’s work, ...

Since then, the periodic table has evolved to reflect over 150 years of scientific development and understanding in chemistry and physics. Today, with 118 known elements, it is widely regarded as one ...

Mrs Roberts: Not quite. So, today we're going to look at the periodic table. That thing that you see behind your teacher on the wall in science lessons. It actually tells us a lot about the ...

The story of the last element to be discovered out of the first 92 catalogued in the periodic table is told by Eric Scerri, who reminds us that technetium can be found a little closer to home than ...

in an attempt to memorise some of the 118 elements. 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 ...

Superheavy elements are those elements with a large number of protons in their nucleus. Elements with more than 92 protons are unstable; they decay to lighter nuclei with a characteristic half-life.

This puzzle shows many of the elements used to make transistors. The finished puzzle is a section of the periodic table, so the numbers on each tile are their atomic numbers - that means they ...

Electronegativity, an essential characteristic of all elements in the periodic table, measures an atom's ability to attract electrons towards itself within a chemical bond. This vital theoretical ...

Global automation design based on smart devices, IoT, distributed control systems, data analytics, digital twins and advanced engineering tools allow ... efficiency and the development of large ...
