trigonal

基本解釋

So it's trigonal pyramidal.
所以它是三角形金字塔。
The shape is actually trigonal pyramidal.
它的形狀是三角金字塔形。
So it's trigonal because we have these three atoms that are bound to the central atom here, and if you picture it, it's actually shaped like a pyramid.
這里三角形是因為,我們有3個原子核中心原子成鍵，如果你畫它，它就是金字塔形的。

So what we'll have here is a trigonal planar case, and you can see that we only have three electrons that are set for bonding, so we'll add three hydrogens, and for b h 3, we'll get a stable structure here.
讓電子勁量遠離的時候，不用考慮它,這個例子是平面三角形，你可以看到，只有3個電子可以成鍵。

So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.
如果我們考慮碳原子的形狀，它是平面三角形，鍵角是，因為我們有這三個雜化軌道。
