1 00:00:01,199 --> 00:00:20,940 Ions. What are the ions? An ion is an atom that has a positive or negative 2 00:00:20,940 --> 00:00:32,460 charge. This is an ion. Types of ions. Negative ions. An ion is negatively charged and forms 3 00:00:32,460 --> 00:00:36,079 when an atom gains electrons. 4 00:00:36,079 --> 00:00:38,820 Positive ions. 5 00:00:38,820 --> 00:00:43,880 A positive ion kills electrons. 6 00:00:43,880 --> 00:00:45,359 Parts of atoms. 7 00:00:45,359 --> 00:00:48,020 Electrons, protons, and neutrons. 8 00:00:52,979 --> 00:00:54,799 The end.
