The atomic mass of 12CC is 12 Da, and the atomic weight of 12CC is 12 exactly. All other atomic weight values are ratios to the 12C standard value and thus are dimensionless numbers." age showing periodicity of standard atomic weights for 5s, 5p, and 5d chemical elements....
根据本句空前“Just as chemists arranged elements in the periodic table by their atomic weight and group (就像化学家在元素周期表中按原子量和基团排列元素一样)”以及空后“new insights(新的见解)”可知,化学家这样做来解释新的见解。故选C。 (5)题详解: 考查名词词义辨析。句意:研究人员希望通过不同...
