An isotope of hydrogen with one proton and one neutron in the nucleus having anatomic weightof 2.04.───氢的一种同位素,在其原子核内有一个质子和一个中子,其原子重量为2.04。 Theatomic weightis a ratio quite distinct from the weight in grams.───原子量是与以克为单位的重量完全不同的比率....
美 英 na.【化】原子量 复数:atomic weights 权威英汉双解 英汉 英英 网络释义 atomic-weight — see also relative atomic mass 释义: 全部,原子量
atomic weight The average mass of a chemical element, expressed in atomic mass units. The atomic weight of an element having more than one principal isotope is calculated both from the atomic masses of the isotopes and from the relative abundance of each isotope in nature. For example, the at...
