Shape step three The water molecule (left) illustrates an excellent polar thread that have a slightly self-confident charge towards hydrogen atoms and you may a somewhat bad charges towards the outdoors.

The brand new chlorine atom have eight electrons in exterior cover. Again, it is much more times-successful for chlorine to gain that electron rather than get rid of 7. Therefore, it will acquire a keen electron to produce an ion having 17 protons and you can 18 electrons, providing they an online negative (–1) charges. It is now titled a good chloride ion. So it movement out-of electrons from ability to another was known so you’re able to given that electron import. Because the Profile 1 illustrates, a salt atom (Na) only has one electron within the outermost cover, while a beneficial chlorine atom (Cl) provides eight electrons in outermost layer. A salt atom usually donate their you to definitely electron to blank its layer, and you can a good chlorine atom encourage one to electron to complete their layer, is chloride. (more…)
