If an atom has all of it's outer orbitals filled it is non-reactive.
Reactivity of chemical elements is indicated by their's electronegativity.
Lithium.
Yes, nicotine is chemically reactive.
Yes. It is very reactive.
reactive
No, it is a noble gas.
Lithium.
No. argon is chemically unreactive due to the presence of completely filled orbitals.
The anion has a negative electrical charge and is more chemically reactive than the atom.
Yes, nicotine is chemically reactive.
the one that is completely filled
All the neutral atoms (except noble gases) are more reactive. To gain stability, they form ions; therefore, ions are less reactive.
The most chemically reactive ion is the hydrogen ion.
Yes. It is very reactive.
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
Unstable isotopes can be chemically reactive.
Manganese is not radioactive; chemically is sufficiently reactive.
yes it is
