And when we talk about covalent bonds, there's 2 properties that we'll mostly focus on, and that's going to be thinking about the bond strength or the energy by which it stabilized when it bonds.
而当我们讨论共价键的时候,有两点特性是我们最关注的,那就是键的强度,或者说成键之后能量降低了多少。
And what we've been talking about with all of these properties are, of course, how can we figure out what that is for a certain atom by looking at the periodic table, so we want to think about the periodic trend for atomic radius.
