A tetrahedral shape has four faces and four vertices, equally spaced, while a trigonal pyramid has a triangular base and three faces converging to a point above the base.
1.3英文释义:Having the shape of a tetrahedron; consisting of four faces. 1.4相关词汇:tetrahedron(名词,四面体);tetrahedrally(副词,成四面体地) --- 2 起源与背景 2.1词源: “tetrahedral”一词来源于希腊语。“tetra-”在希腊语中表示“四”,“hedra”意思是“底座、面”,所以“tetrahedron”原意就是“有四...
Negative-parity bands in deformed nuclei have traditionally been interpreted in terms of octupole excitations, but interest in these bands has been revived recently by predictions of tetrahedral shape. The level schemes of numerous nuclei in...
There are many common molecules with a tetrahedral shape. Some of these molecules include methane (CH4), phosphate (PO4), sulfate (SO4), permanganate (MnO4) and ammonium (NO4). What are the bond angles of CH4? CH4, or methane, represents a tetrahedral molecule. The bond angles for a te...
