WebBecause Group 1 elements have wide atomic radii between neighbouring atoms, the melting and boiling points are lower than other metals. The atomic radius increases when added an extra shell to the previous element, resulting in lower melting and boiling points down the group. WebFor example, the boiling point of diethyl ether (C 4 H 10 O, molecular weight [MW] 74) is 35 °C (95 °F), but the boiling point of 1-butanol (or n - butyl alcohol; C 4 H 10 O, MW 74) is 118 °C (244 °F).
