7/16

Polyatomic Ions Knowledge (PIK)

Measures how well you can identify common polyatomic ions (names, formulas, charges) and apply charge-balancing to form neutral ionic compounds.

Foundation to Build

Developing Knowledge

Strong Knowledge

0 – 6: Foundation to Build | 7 – 12: Developing Knowledge | 13 – 16: Strong Knowledge

A score of 7 falls in Developing Knowledge, suggesting you recognize many polyatomic ions and can solve some formula problems, though similar names or charge ratios may still lead to mistakes.
