And why did he call it polar covalency?
为什么要称它为极性共价呢？
This is pure covalency. This is polar covalency.
这是平均共价，它是极性共价。
So you can see that polar covalency is a tendency towards ionic bonding.
所以你看得出极性共价就是，趋向离子键的。
This is the homonuclear bond energy for hydrogen in pure hydrogen. There we have perfect covalency.
这是氢的同原子的共价能,在纯氢中，我们有完美的共价键。
This is the homonuclear bond energy for hydrogen in pure hydrogen. There we have perfect covalency.
这是氢的同原子的共价能,在纯氢中，我们有完美的共价键。
