Question

which of the following would be attracted to the positive pole of an electric field? (select all that apply.)
□ al³⁺
□ o²⁻
□ cu²⁺
□ n³⁻
□ ca²⁺
□ h⁺
□ te³⁻

Explanation:

Step1: Recall charge - attraction rule

Opposite charges attract. A positive pole in an electric field will attract negatively - charged particles.

Step2: Identify negative ions

$O^{2 -}$, $N^{3 -}$, $Te^{3 -}$ are negatively - charged ions.

Answer:

O2-, N3-, Te3-
