An ion that consists of 7 protons, 6 neutrons, and 10 electrons has a net charge of

-3

Explanation:

The charge of the ion is determined by the number of protons and the number of electrons.

Protons are a positive + charge.

Electrons are a negative - charge.

We have 7 protons and 10 electrons.

+7 charge

-10 charge

-10 + 7 = -3 charge

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
