What is the charge of an atom containing 9 protons, 11 neutrons, and 12 electrons?

Explanation: atom is changed to ion. There are 3 more electrons than

Protons, so charge is -3. Actually, F atom can gain only one electron.

Then it will have an octet (8 electrons)

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
