一、关于微粒(原子、离子)半径大小的比较本文所提的微粒是指原子、简单阳离子、简单阴离子。微粒半径的大小,对微粒的性质有很大影响,从而导致微粒组成的物质在结构和性质上发生相应的变化。如同一主族或同一周期元素的原子半径越大(稀有气体除外),微粒的金属性越强,越容易失去电子,阳离子半径越大,氧化性越弱;阴离子半径越大,离子的还原性越强等。离子半径的大小,是影响离子晶体空间构型 First, on the particles (atoms, ions) the size of the comparison The particles mentioned in this article refers to the atoms, simple cations, simple anions. The size of the particle radius, the nature of the particles have a great impact, resulting in the composition of the material particles in the structure and properties of the corresponding changes. As the atomic radius of the same main group or elements of the same period is larger (except rare gas), the stronger the metallicity of the particles is, the easier it is to lose the electrons. The larger the radius of the cation is, the weaker the oxidizing property. The larger the anion radius is, The stronger and so on. The size of the ionic radius is the spatial configuration of the ionic crystal
