Ions chemistry notes
WebNote the usefulness of the periodic table in predicting likely ion formation and charge (Figure 2.29). Moving from the far left to the right on the periodic table, main-group elements tend to form cations with a charge equal to the group number. That is, group 1 elements form 1+ ions; group 2 elements form 2+ ions, and so on. WebIons worksheets and online activities. Free interactive exercises to practice online or download as pdf to print.
