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.
no it doesnt
the ion has a greater number of electrons
no. it will be same. only the number of electrons will differ
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.
An ion has a net electrical charge; a nonionic particle that is at least as large as an atom does not.
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 S2- ion has gained two electrons, giving it a 2- charge, while a neutral sulfur atom has an equal number of protons and electrons. This means that the S2- ion has two more electrons than a neutral sulfur atom.
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-
Sodium Ion has lost one electron, to become an ion, Na+.Sodium has one more electron than Sodium ion.Sodium Ion has 2 energy levels of electrons.Sodium Atom has 3 energy levels of electrons.Sodium Ion has 11 Protons, 11 Neutrons and 10 Electrons.Sodium Atom has the same number of protons (11) ,neutrons (11) and electrons (11).
what does an atom have in common with an ion?
An ion exists as an atom or a molecule where the total number of protons in the nuclei do not equal the atom/molecule's electrons. An example is Ca2+. It has 2 less electrons than it has protons.
