Atomic and physical properties of elements of group 16, 17 and 18

The atomic properties (radii, ionisation enthalpy, electronegativity, electron gain enthalpy) and the physical properties (density, melting and boiling points) of the elements of groups 16, 17 and 18 are collected in Tables 7.2, 7.3 and 7.4 of the next subsection, and the trends they reveal are discussed prope …
