Predicting Ions

Flashcards covering key rules and concepts for predicting ion charges based on position on the periodic table.

Group 1 metals

Metals that form $+1$ cations based on their position on the periodic table.

Group 2 metals

Metals that form $+2$ cations based on their position on the periodic table.

Group 5A elements

Elements listed as forming $-1$ anions based on periodic position.

Group 6A elements

Elements that form $-2$ anions based on periodic position.

Group 7A elements

Elements listed as forming $-3$ anions based on periodic position.

Transition and lower main group metals

Metals that have varied charged on cations.

Stairstep ions

Specific metals with fixed charges to remember: silver ($\text{Ag}^+$), zinc ($\text{Zn}^{2+}$), and aluminum ($\text{Al}^{3+}$).
