an atom with a positive or negative net charge is called an ion. select all of the models of ions.
Answer
Brief Explanations:
An ion has a positive or negative net charge, meaning the number of protons (positive charges) does not equal the number of electrons (negative charges). Models showing unequal proton and electron counts represent ions.
Answer:
[Assuming the first model has 1 proton and 0 electrons (net +1 charge), the third model has 3 protons and 2 electrons (net +1 charge), these would be correct. Since the exact counts depend on the visual, but based on standard ion definition, select models where proton count ≠ electron count.] (Note: In the actual scenario, the user would select all models where the number of protons differs from electrons, which are the ionic models as per the definition provided.)
