电子非常轻,因此在原子量中甚至没有计算它。
Electrons weigh very little, so they aren't even counted in the atomic weight.
各种原子的原子量是不同的。
具有不同原子量的同一种元素被称为同位素。
Atoms of the same element that differ in their atomic weight are called isotopes.
And the other thing to point out, which I don't know if this is true or not, but does anyone know -- well that's part's true, does anyone know what the atomic mass of lithium is?
另外需要指出的一点是,关于这点我不知道是不是真的,有人知道--这部分是真的,有人知道锂的原子量吗?
So, even though we don't have the lithium anymore, we still keep that atomic number 7 around.
尽管现在它不含锂了,但是作为原子量的七,还是在一定程度上保留了下来。
And now we're asking you to look at krypton, so the atomic mass is 36. You can actually just grab that handout the second handout on the exam and look at the periodic table there. So, which of the following ions listed is isoelectronic with krypton?
现在我们请大家来看一下氪原子,它的原子量是,36,大家其实可以拿出这张讲义,第二份关于考试的讲义,看一下上面的周期表,那么,下列离子中,哪一个是与氪原子是等电子的?
