Question

What is TRUE about the ion below with a - 2 charge? MULTI SELECT-2.

Answer 1

I can’t see the ion you mean. Paste the image or the answer choices and I’ll pick the two correct statements.

Meanwhile, here are general facts that are always TRUE for any ion carrying a −2 charge (pick the ones that match your choices):
- It is an anion (negatively charged ion).
- It has two more electrons than protons.
- It was formed by gaining two electrons.
- Its total number of electrons = atomic number + 2.
- Its oxidation state/charge is −2.
- Its ionic radius is larger than the neutral atom’s radius (extra electron–electron repulsion).
- Its mass number (number of protons + neutrons) does NOT change when the ion forms.

And things that are FALSE for a −2 ion (common distractors):
- The nucleus lost or gained protons/neutrons (false — nucleus unchanged).
- It has fewer electrons than the neutral atom (false — it has more).
- It is attracted to the negative electrode (false — negative ions are attracted to the positive electrode/anode).

Send the specific choices and I’ll mark the two correct ones.
