How big are ions
Did you know?
An ion is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. Web4 de set. de 2024 · Anions are ions that carry a net negative charge. In anions, there are more electrons than protons. The number of neutrons is not a factor in whether an atom, …
