Question

multiple - choice question
what type of compounds form positive and negative ions?
covalent
ionic
both
rewatch

Explanation:

Step1: Understand ionic compounds

Ionic compounds are formed by the transfer of electrons from one atom to another.

Step2: Analyze ion formation

In ionic compounds, one atom loses electrons (forms positive ion - cation) and another gains electrons (forms negative ion - anion).

Step3: Contrast with covalent compounds

Covalent compounds share electrons and do not form ions in this way. So the answer is ionic.

Answer:

B. ionic
