An atom is the smallest component of any element having all the chemical properties of that specific element.
A molecule is the simplest complete structural unit of an element or compound that can exist in nature.
Ions are atoms or molecules that have become electrically charged (positive or negative) by having lost or gained one or more electrons.
Oxidation is the loss of electrons or an increase in oxidation state by a molecule, atom or ion. Reduction is the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion.
An ion is a positively or negatively charged atom or molecule.
a molecule is more than one atom attached together, an ion is an atom/molecule where the number of electrons is not equal to the number of protons in the nucleus
ion
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-
A molecule or an ion that is bonded to the central atom of a complex ion is called a ligand. Ligands can donate pairs of electrons to the central metal atom or ion, forming coordinate covalent bonds.
Sorta, a molecule can neither be positive or negative and atom can only be an ion when in an ionic bond when it received or gave electrons.
An "Ion" is an atom that has gained or lost an electron and is therefore no longer electrically neutral.
The nitrite ion has one less oxygen atom.

'Fluoride atom'. ???? The fluorine ATOM is 'F' The fluorine molecule is 'F2'. The Fluoride ION is 'F^-' NB When an atom becomes a charged species, it is no longer an atom , but an ION. The suffix '--ide' indicates it is an ion, not an atom. So 'Fluoride atom' is a nonsense. It is either 'Fluoride ion' or Fluorine atom'.
A sodium (Na) atom is neither an ion nor a molecule. It is a single, neutral atom with 11 protons in its nucleus and 11 electrons orbiting around it. An ion is when an atom gains or loses electrons to become charged, and a molecule is a combination of atoms bonded together.
