自从冥王星在2006年被剔出太阳系大行星之列以来,现在最震撼科学界的大事,当数化学元素原子量的全面改动了。以前化学元素周期表上的原子量只是一个大致估计,并不精确,今后氧、氢、锂、硼、碳、氮、硅、硫、氯和铊这10种元素的原子量将以数值区间方式标注,而不再只是一个失真的单一数值(如图)。这一变化也表明长期以来,科学界终于承认118种元素中大部分的原子量是变化的。
Since Pluto was knocked out of the solar system’s asteroid in 2006, the most shocking event for the scientific community now is the complete change in the atomic weight of several chemical elements. The previous atomic mass of the periodic table of chemical elements is only a rough estimate and not accurate. The atomic weights of the 10 elements of oxygen, hydrogen, lithium, boron, carbon, nitrogen, silicon, sulfur, chlorine and thallium will be numerically marked in the future, Instead of just a single value of distortion (pictured). This change also shows that, for a long time, the scientific community has finally admitted that the atomic weight of most of the 118 elements is changing.
