离子与原子是两个既相互区别又相互联系的概念。现将它们的区别与联系作一归纳。一、区别1．实质不同。原子是化学变化中的最小微粒，也就是说，在化学变化中，原子不能再分解成更小的微粒，也不会变成其他原子；而离子是带了电荷的原子或原子团，当原子或原子团得到或失去电子 Ions and atoms are two concepts that are distinguished from each other and are related to each other. We will now summarize their differences and connections. First, the difference 1. Substantially different. An atom is the smallest particle in a chemical change. That is to say, in a chemical change, an atom can no longer break down into smaller particles, nor can it become other atoms; ions are charged atoms or atom groups, when atoms or Atomic groups get or lose electrons
