When is an atom electrically neutral?
August 27, 2021 | education|
Explanation of the solution to the problem: the atom is always electrically neutral, this is one of the provisions of Rutherford’s theory, which sounds like “the atom as a whole is electrically neutral.” This means that the number of protons (positive particles) in an atom is always equal to the number of electrons (negative particles), while the protons are concentrated in the nucleus (therefore it has a positive charge), and the electrons revolve around it. And if the particle has a charge, then it is already an ion, and if the charge is positive, that is, there is an excess of protons in the atom, then it is a cation, and if it is negative (excess of electrons), then an anion.
