All ions are charged- either positive or negative - there is no such thing as a neutral ion- an ion is a charged atom e.g. Na+ (sodium atom lost 1 electron), Cl- (chlorine atom gained 1 electron) or a molecule (chemists call these polyatomic ions) - e.g. SO42-
No, ions are always charged.
by definition, ions are charged atoms. so a neutral ion doesn't exist
No, it's the opposite. An ion is a charged atom, that is an atom with more ("anions" - charged negatively) or less ("cations" - charged positively) electrons, in comparision with the fundamental (neutral) state.
no it doesnt
the positive and negative energy is no longer in balance causing the atom to become an ion+ or an ion-
An ion is a charged particle. A sodium atom is neutral and has one electron in the valence shell. When it loses its valence elctron, it is no longer neutral and becomes Na+ , i.e a charged particle, hence it is an ion.
no. it will be same. only the number of electrons will differ
No. NO2 (nitrogen dioxide) is a neutral molecule and NO2-, (nitrite ion) is a negative ion
no. atomic number will be same as the number of protons will not change for an ion and its neutral atom, but the number of electrons will vary.
This neutral atom become a cation or an anion.
An "Ion" is an atom that has gained or lost an electron and is therefore no longer electrically neutral.
1. Ammonia (NH3) is a neutral molecule. 2. Ammonium (NH4+) is a cation (a positive charged ion).
