even atomic number 偶数原子序数
number effective atomic 有效原子序数
Atomic number or proton number 原子序数或质子数
material low-atomic-number 低原子序物质
All the isotopes of a given element have the same number of protons, but differ in their number of neutrons, and hence in their atomic mass.
给定元素的所有同位素都含有相同的质子数,但它们的中子数不同,因此它们的原子质量也不同。
Early versions had the incorrect atomic number for some elements.
早期版本的一些元素原子序数不正确。
Early versions did not list an element for every atomic number.
早期的版本并没有为每个原子序数列出一个元素。
That is why this says atomic number, but for most intents and purposes we can say this could be atomic mass.
那就是为什么这里说原子序数,但如果没有意图和目的,我们就说是原子质量。
If you look on the Periodic Table this is 598 atomic hydrogen. And, sure enough, there is 13.598, which is this number here in electron volts.
如果你查找元素周期表上的氢原子,毫无疑问,它的电离能就是13。,这个数值也是电子伏的值。
So similarly, as we now move up only one more atom in the table, 3 so to an atomic number of three or lithium, now we're going from six variables all the way to nine variables.
类似地就像我们现在,移动到周期表中仅仅多一个电子的情况,移动到一个原子数为,或者锂元素,现在我们从6个变量到了9个变量。
