Odd Mass Number Ho Isotope 奇质量数Ho同位素
But the nitrogen in the air was replaced with a nitrogen atom with a different number of neutrons, called an isotope.
但是空气中的氮气中的氮原子却会被一个叫做同位素的有着不同数量中子的氮原子所替换。
The number after the element name identifies the specific isotope.
元素后面的数字表明特定同位素的身份。
The highest known magic number for neutrons alone is 126. Lead, with 82 protons and 126 neutrons, is thus "doubly magic" and the heaviest stable isotope in the periodic table.
目前已知的最大中子数是126,82个质子和126个中子组成了元素周期表中最重最稳定的同位素。
