an axial electron pair meets at right angles with 3 neighboring pairs . 軸向電子對(duì)與三個(gè)相鄰的電子對(duì)相交成直角。
in this model the arrangement of bonds around the central atom is considered to depend upon how many valence-shell electron pairs . 在這個(gè)模型中,認(rèn)為圍繞中心原子的化學(xué)鍵的排列取決于價(jià)層中電子對(duì)的數(shù)量。
correlated electron pair approximation 相關(guān)電子對(duì)近似
the number of electron pairs an atom can share with other atoms 共用電子對(duì)數(shù),共價(jià)一個(gè)原子與其他原子共用的電子的對(duì)數(shù)
