Ions activity
WebHow We Introduce this Activity We typically introduce this activity with an informal quiz about chemical formulas, asking students to tell us how many atoms are in a particular neutral ionic compound (e.g. How many aluminum atoms are in aluminum oxide?) or the name corresponding to a particular chemical formula. (e.g. What is the name of FeCl 2?)
