The Goldhammer-Herzfeld ratio of these substances is nearly one. The oxides of these elements are used in glassmaking, and these elements are used to dope semiconductors. As it is lustrous yet brittle, (*) selenium is sometimes considered in this group, which includes germanium, boron and silicon along the staircase of the periodic table. For 10 points, give this term for elements with both metal and non-metal properties.
