Lowest melting and boiling point
WebThis list contains the 118 elements of chemistry. For chemistry students and teachers: The tabular chart on the right is arranged by melting point. The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon. The unity used for the melting point is Celsius (C). WebThe low melting points for the light to middle lanthanides are thought to be due to a 4 f electron contribution to the bonding, which is a maximum at cerium and decreases with increasing atomic number to about zero at erbium. The low melting points of europium and ytterbium are due to their divalency. Boiling point s
