He was the first person to recognise the periodic trends in the properties of elements, and the graph shows the pattern he saw in the atomic volume of an element plotted against its atomic weight. A ...

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 ...
