These are all one electron atoms, and they are gas, a single atom.
这些都是单电子原子,它们都是气体,都是单原子。
Ionized by energetic starlight, a hydrogen atom emits the characteristic red H-alpha light as its single electron is recaptured and transitions to lower energy states.
氢原子被高能的恒星光离子化之后,在它的单个电子重新被捕获并跃迁到低能级上时会放出典型的红色h - alpha光。
One can picture this single electron spin caught on the nanotube as an artificial atom, " says researcher from University of Copenhagen and participant in the study, Jonas Hauptmann.
人们也可以把被碳纳米管捕捉的单电子自旋当成一个人造的原子。” 哥本哈根大学研究员,这项研究的参与者,Jonas Hauptmann 说。
We're going to get to more complicated atoms eventually where we're going to have more than one electron in it, but when we're talking about a single electron atom, we know that the binding energy is equal to the negative of the Rydberg constant over n squared, so it's only depends on n.
我们以后会讲到,更加复杂的情况,那时候,不只有一个原子,但当我们讲,单个原子的时候,我们知道结合能,等于,负的Rydberg常数,除以n平方,所以它仅仅由n决定的。
So we can actually pop an electron or eject an electron from any single orbital that is occupied within the atom.
任何一个被占据轨道,打出一个电子,或者说发射出一个电子。
These are all one electron atoms, and they are gas, a single atom.
这些都是单电子原子,它们都是气体,都是单原子。
