You'll increase the total volume of food, spreading out the sodium over more servings.
你将会增加食物的总数,却减少了饮食中过量的钠。
Instead of energy consumption, however, these food stars would track levels of three often over-consumed nutrients: saturated and trans fats, added sugar, and sodium.
然而,与检测能源消耗量不同,食品的星级标准检测的是三个经常过度食用的营养成分的级别:饱和(不饱和)脂肪,添加糖分和钠。
So, for example, if I have a sodium ion over here, and I have a chloride ion over here, where the distance from center to center r I'm denoting as r, this is nucleus to nucleus separation.
所以,比如这有一个钠离子,和一个氯离子,它们中心与中心间的距离,我把它设为,这是原子核和原子和的间距。
And so what you're going to end up with is, well, let's go over that. Here is sodium and chloride.
你将以之结尾,好吧,我们跳过那个,这是钠和氯。
So, the sodium over here and the chlorine over here, they will be attracted to one another.
当钠离子和氯离子在一块时,它们会相互吸引。
If you flip the Periodic Table over you will have the ionization energy of sodium, first ionization energy, 5eV and it is about 5 eV which, when you convert, 496kJ/mol is a whopping 496 kilojoules per mole.
如果浏览周期表,你可以得到钠的离子化能,第一电离能,大约,当你转换的时候,是巨大的。
