Because these things are unpaired, we have already seen how unpaired electrons play a role in the Stern-Gerlach experiment.
因为这些事物都是未成对的，我们已经发现在 Stern-Gerlach实验中，未成对电子扮演怎样一个角色了。
Light hitting the proteins produces a pair of free radicals, highly reactive molecules with unpaired electrons.
光击中这种蛋白质产生一对游离的活性基，这是一种非常活跃的有着不成对的电子的分子。
S — we don't have to hybridize it, it already has only one unpaired electron in a 1 s orbital.
s -我们不用杂化它，它已经有而且仅有一个未配对电子在s轨道里。
And what I want to point out that we just figured out for molecular orbital theory, is that o 2 is a biradical, because remember, the definition of a radical is when we have an unpaired electron.
我要指出的是，我们刚利用分子轨道理论，指导了O2是二价自由基，因为记住，自由基的定义是，有个未配对的电子。
Literally, a radical is a molecule that reacts easily with other chemicals because of an unpaired electron.
精确地说，因为有孤电子，所以分子中的基团与其他化学物质反应更加容易。
A free radical is a molecular fragment having an unpaired electron.
自由基是一种具有未配对电子的分子碎体。
An atom or a group of atoms with at least one unpaired electron.
原子因，基团，至少有一个游离电子的原子或一组原子。
The results showed that 4.53% of PMCs contained at least one unpaired of chromosomes and 2.31% of PMCs had a chromosome number deviating from their normal Numbers.
结果表明，4.53%的细胞含有至少一对不配对的染色体，2.31%的细胞里，染色体偏离正常的数目。
When the atom absorbs energy from light, one electron may move to a higher energy orbit, leaving an unpaired electron.
当原子从光吸收能量，一个电子可移动到一个更高的能量轨道，留下一个未成对电子。
When the atom absorbs energy from light, one electron may move to a higher energy orbit, leaving an unpaired electron.
当原子从光吸收能量，一个电子可移动到一个更高的能量轨道，留下一个未成对电子。
