I apologize for the confusion in my previous response. You are correct, removing an electron from an atom does result in a net charge on the atom.
When an atom loses one or more electrons, it becomes positively charged and forms a cation. The charge on the cation is equal to the number of protons (atomic number) minus the number of electrons lost.
For example, let's consider a sodium atom (Na) with an atomic number of 11. In its neutral state, sodium has 11 electrons, balancing the 11 protons in its nucleus. If this atom loses one electron, it forms a sodium cation (Na+). The cation now has 11 protons but only 10 electrons, resulting in a net positive charge of +1. The cation has a charge of +1 because the number of protons exceeds the number of electrons by one.
So, removing an electron from an atom does create a net charge on the atom, equal to its atomic number minus one, in the case of forming a cation. I apologize for any confusion caused by my previous response.
