an ion has either more or less electrons then a neutral atom. electrons have an electrical negative charge so if you have too many of them you get a negative ion like Cl- and if you have too few you get a positive ion like Na+
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
The ion formed by a fluorine atom is called a fluoride ion, which has a charge of -1. It is formed when a fluorine atom gains an electron to achieve a full outer electron shell.
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
No, a hydrogen ion (H+) is a positively charged hydrogen atom that has lost its electron. A negatively charged hydrogen atom would be called a hydride ion (H-).
Yes, the number of protons in an atom and its ion of lithium is the same. Lithium always has 3 protons in its nucleus, regardless of whether it is in its neutral atom form (Li) or as an ion with a different number of electrons.
The nitrite ion has one less oxygen atom.
An "Ion" is an atom that has gained or lost an electron and is therefore no longer electrically neutral.
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).
