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 ...

"It all started when we decided to calculate Pauling's electronegativities under pressure,” explains Prof Artem R ... Electronegativity and ionization energy follow the same periodic table trend.
