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 ...

There is no experimental data for francium, but its ionization energy is higher than that of cesium, so it is expected that francium is slightly more electronegative. Electronegativity generally ...

As you move from left to right across the periodic table, atoms have more electrons in their outer energy level and more protons in their nucleus. The greater attraction between the increased ...
