可以由离子的化学势算物质的么?...

这是专家写的:Indeed, we can freely choose as many zero points as there are chemical elements7.
Chemists make this choice so that the potential of every element is zero when it is in its most
stablemodification and under standard conditions (conventional scale). A less arbitrary choice
would be to take the elements as isolated atoms at rest (atomic scale).
这是部分相对大小
