atomic nucleus that makes up an atom carries a positive charge, while electrons carry a negative charge. Since electrons are light, they move very quickly around the nucleus. Some of these light electrons can easily move to other atoms. Therefore, atoms can either chase or move electrons. If electrons are running, the atom becomes negatively charged. If an atom loses a charged electron, it loses its positive charge. When an atom becomes charged by gaining or losing electrons in this way, the resulting particle is called an ion. An electron gains an electric charge (0), and when it gains a positive charge (0), the particle is called a cation. When representing this, we use a binary system with element symbols. For example, on the right side of the 5, we indicate a minus sign when an electron is gained and a plus sign when an electron is lost. We represent it as 2 min if it has two electrons and 2 plus signs when it has two. Also, there are atoms that are formed by the combination of multiple atoms, not just a single one. Examples of ions include ammonium ions, sulfuric acid ions, and carbonate ions. When naming, in the case of cations, 'rat's divorce' is attached, and if meaning follows, an additional character is added, such as 'Eohwa No. 2' or 'San-i Yong'. The key point regarding recovery, which carries this kind of power, is that it continues this year. Distilled water, which poses no danger, does not conduct electricity, but when theory is introduced, electricity flows. If electricity is passed through swimming water containing dissolved ions, the cations move to the negative pole (meaning), and through the movement to the positive pole, one can confirm the electrical properties of the ions. Also, to use an analogy, an electron is a ring. If the particle has divorced, it will be ready to flirt. When there are people who have a limit on rings, people who have left indignantly, and people who have worn three rings, there are those who can wear three rings, or even two rings. Now, by matching the amount of rings one can give and the amount one can wear, they meet and become a couple. Furthermore, even if they become lovers, there are couples who meet trials and break up, and there are couples who break up immediately. Oh my, if you mix a two-room water solution with a silver nitrate solution, a white, non-dissolving dark gold is created this year. Romana It is about the doctor meeting the main solution and all kinds of silver nitrate solutions to form a silver chloride precipitate. Too much ion and low lust nitrate ion meet the flowing 5 and break up like coffee, and too much ion and are a couple that made it impossible by crossing the finish line to marriage inside today's tears. The nitrate heart remaining inside is still dissolved and bound in the water. The reaction where measured cations and anions react to produce an insoluble precipitate is called a precipitation reaction; you just need to know a few representative types. If you know how much electron is missing and how much rises to cause a divorce, you can break up inside and meet the best to create glasses, matching these four types. In this session, we looked into what temperature is, the method of this clothing being a text, ions by the roadside, and finally, the precipitation formation cartoon a again regarding precipitates. Until now, we have been with the welcoming but encouraging teacher, but burned
