离子势（ionic potential）是指离子电荷数（Z）和离子半径（r，pm）之比值（用Ф表示），即Ф=Z/r。
结果表明：蛭石晶层的层间距主要受层间水分子层数的影响，而后者又主要由层间阳离子的离子势大小决定。
The results indicate that the interlayer space is influenced by the layers of water molecules which is decided by ionic potential of interlayer cations.
随着层间阳离子离子势的增大，其层间水脱失温度增高，层间水的对称伸缩振动频率降低，弯曲振动频率提高。
With the increase of ionic potential, the dehydrated temperature and the bending vibration frequency of interlayer water increase, and strength vibration frequency decreases.
在过渡金属中，银的二阶电离势最高。 在常温下，HF溶剂化的Ag2+离子可氧化Xe生成XeF2。
The HF-solvated Ag2+ ion (silver has the highest second ionization potential of any transition metal) oxidizes Xe at ordinary temperatures (Zemva et al., 1990) to make XeF2.
