15 sie 2024 · Learning Objectives. Know how ions form. Learn the characteristic charges that ions have. Construct a proper formula for an ionic compound. Generate a proper name for an ionic compound. So far, we have discussed elements and compounds that are electrically neutral.
You can use periodic table trends to predict the most common element charges. Group I (alkali metals) carry a +1 charge, Group II (alkaline earth metals) carry a +2, Group VII (halogens) carry -1, and Group VIII (noble gases) carry a 0 charge.
Watch a video that explains how atoms can gain or lose electrons to form ions, and how ions are represented by symbols and charges.
Ion Definition. Table of Ions. “An ion is a small electrically charged particle. Ions are single charged atoms (simple ions) or small charged “molecules” (polyatomic ions).” Simple ions include Na +, Ca 2+, and Cl –. Polyatomic ions include (NH 4) +, (CO 3) 2-, and OH –.
Ionic bonding occurs when atoms lose and gain electrons to form ions and then the positively and negatively charged ions are attracted to each other. In this activity, learners will gain an understanding of the models and diagrams used to represent this and their limitations.
