Anything that is unstable is more reactive, and anything that is stable is less reactive. Since a charged ion requires energy to maintain its charge, it is LESS stable and thus MORE reactive.
is an atom or an ion more reactive
F
Francium is more reactive.
An atom can become a positive ion, or a cation (cat-ion), when it ''gives'' away one or more electrons. An atom becomes a negative ion, or an anion (an-ion), when it gains one or more electrons. Atoms that do this do not have completely filled valence shells, and are therefore reactive. To become unreactive, they have to either gain or lose electrons to have a filled valence shell and thus gain a noble gas configuration. Hope you understand! :D
Fluorine would be more reactive. Fluorine is the most reactive element.
The Mg atom has more electron than the Mg+2 ion.
F
All the neutral atoms (except noble gases) are more reactive. To gain stability, they form ions; therefore, ions are less reactive.
Fluoride is an ion; it is basically fluorine that has already reacted. As such it is fairly stable. Elemental fluorine is much more reactive that carbon.

An ion is a electrically charged atom (negative ion) has more electrons that protons and positive ion has more protons that electrons)
The most chemically reactive ion is the hydrogen ion.
Fluorine would be more reactive. Fluorine is the most reactive element.
A charged atom is an ion. An atom that has lost one or more electrons becomes a positively charged ion called a cation. An atom that has gained one or more electrons becomes a negatively charged ion called an anion.
The sulfur atom can be reduced to form a sulfide ion which has an octet of electrons in the outer shell. While the S2- ion may be more stable electronically than a bare S atom it is quite reactive . The sulfide ion reacts with water forming the HS- ion. In slightly acid solution n it forms H2S Many metal sulfides are in fact best described as covalent compounds, such as the transition metal sulfides.
The atom had either lost or gained one or more electrons forming and ion. Thus the ion has an overall electric charge.
If the atom has more electrons than protons, then yes it is an ion.
