(一)离子的真实性原子、原子团於丢失或加合电子後,成为一个带电的粒子,称为离子。离子按其电荷可分为正离子与负离子,按其电價分为單價离子、二價离子等,又可按其組成分为单原子离子与多原子离子,后者一般称为络合离子。盐类熔融后一般能导电,在这样的场合下,电的输送者是鹽中的正离子与负离子。盐的溶液一般亦能导电,电的输送者亦为离子;盐溶液冰點降低的程度亦说明,盐类一般以离子的形式存在於溶液中。在一般无机化合物中,组成晶体的粒子亦为带电 (A) the authenticity of ions Atoms, atoms in the lost or adducted electrons, as a charged particles, called ions. Ions can be divided into positive ions and negative ions according to their charges, which are divided into monovalent ions and divalent ions according to their electricity rates. They can be classified into monatomic ions and polyatomic ions according to their composition, which is generally called complex ions. Salts are generally conductive after melting, in such cases, the carriers of electricity are salts of positive and negative ions. The salt solution is also generally conductive, the electrical transporters are also ions; the degree of freezing of the salt solution also shows that the salt is generally present in the form of ions in solution. In general inorganic compounds, the particles that make up the crystal are also charged
