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.
如果我们考虑碳原子的形状,它是平面三角形,键角是,因为我们有这三个杂化轨道。
So, if we say that in this entire plane we have zero probability of finding a p electron anywhere in the plane, the plane goes directly through the nucleus in every case but a p orbital, so what we can also say is that there is zero probability of finding a p electron at the nucleus.
而只要是p轨道,这个平面都直接,穿过原子核,那么我们,可以说在原子核上,找到一个p电子的概率为零。
But in sigma orbitals, you have no nodal planes along the bond axis, so if we had a nodal plane here, we'd see an area where the wave function was equal to zero.
但在sigma轨道里,沿着轴向是没有节点平面的,如果我们有个节点,我们就会看到某个地方波函数等于0。
