The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius. Many scientists worked on the ...

The covalent radius (a measure of how large individual atoms are) shows different trends if you are moving ... As you move from left to right across the periodic table, atoms have more electrons ...

The periodic table arranges all the chemical elements in a specific way. Patterns are visible in the way that elements behave, and this allows us to make predictions about other elements.

Electronegativity and ionization energy follow the same periodic table trend. Elements that have low ionization energies tend to have low electronegativities. The nuclei of these atoms don't exert a ...

National Periodic Table Day, observed annually on February 7, honors one of the most significant achievements in scientific ...

What's more, to the surprise of most chemists and going against the well-known trends of the periodic table, it turns out that francium is not the most reactive metal. On descending a group in the ...

Forget 10 Downing Street or 1600 Pennsylvania Avenue, the most prestigious address in the universe is number one in the periodic table, hydrogen. In science, simplicity and beauty are often equated - ...
