He saw that if you take the atomic mass of chlorine, 2 add it to the atomic mass of iodine, divide by two, you get something that is really close to the atomic mass of bromine.

Any element-specific physical signal can be exploited for the identification of atoms in the material, these are the atomic mass, electronic energy levels, nuclear spin and even the local electronic density of states at surface, etc.

任何具有元素特征的物理信息，包括原子量、电子的能级、原子核自旋，甚至局域的电子态密度等都可以用来做材料的化学分析。

And so you can look, for example, at the Periodic Table And, if you look up the atomic mass of carbon, 011 you will see that carbon comes at12.011 for carbon.

如你们所见，例如，在周期表中，如果你观察碳的原子质量，你会看到是12。

I mean, the atom has a tiny mass, too, but what we are saying is compared to the totaled atomic mass, the mass of the electron is tiny.

我的意思是，原子的质量也很小，但是我们说的是，和整个原子质量相比，电子的质量是很小的。

The results show that the motion of atomic mass centre leads to the periodic evolution of the dynamics of the field phase and this period depends on the field mode structure parameter.

结果表明：原子质心运动导致场相位动力学的周期性演化，场模结构参数决定其周期的大小。

And he found that the middle member of the triad had an atomic mass that was midway between the atomic masses of the end members.

他发现三元组中间的元素，的原子质量，是位于两端的元素的原子质量，的中间。

This is12.011 grams per mole or12.011 atomic mass units, AMU.

这是12。011克每摩尔，或者12。011原子质量单位。

It is a double column, You can see, it starts with hydrogen and goes to mercury in ascending order of atomic mass.

双纵栏，你们看到，从氢开始，然后到水银，按原子质量的升序排列。

Mendeleev is the one who taught us that the properties of the elements are a function of the atomic mass.

门捷列夫教授我们元素特性，是元素质量所起的功能。

The elements, if arranged according to their atomic mass, exhibit an evident periodicity of properties.

元素，如果按照他们的原子质量来安排，则它展示了一个明显的周期特性。

( physics, chemistry) being or containing an isotope with greater than average atomic mass or weight.

（物理学，化学）指原子质量或者原子量大于平均水平的同位素，或者含有这样的同位素。

You can plot data for a range of elements for properties like the density or the atomic mass.

你也可以使用一定范围内元素的密度、原子质量等元素性质来构建图表。

And he was very proficient at measuring atomic mass.
