Please do the maths before you speak the charged particle has not gotten an even amount of cancelling forces on it. The forces only cancel right at the center of the sphere.

This is incorrect. As @dRic2 says, the electric field from a charged sphere is zero inside, and hence the force on a charge inside the sphere is zero. This is a standard result, the maths for which was done by Gauss over two centuries ago. See, for example, Wikipedia.Please do the maths before you speak the charged particle has not gotten an even amount of cancelling forces on it. The forces only cancel right at the center of the sphere.

Wikipedia said:We can use Gauss's law to find the magnitude of the resultant electric field E at a distance r from the center of the charged shell. It is immediately apparent that for a spherical Gaussian surface of radius r < R the enclosed charge is zero: hence the net flux is zero and the magnitude of the electric field on the Gaussian surface is also 0

Then remove the oxygen ions.

How, exactly?

then give the sphere a negative charge

How much exactly?
