依据这个新标度,原先的化学原子量数值只需作很小的变动。
The new scale required only minimal changes to the values that had been used for chemical atomic weights.
它们有相同的原子序数,因此化学行为几乎完全一样,但原子量不同。
They have the same atomic number and hence nearly identical chemical behaviour but different atomic masses.
周期表(1869):所有的化学元素按它们的原子量逐渐增加的顺序有组织地排列。
